Romanian decision to introduce nuclear power was based on the evaluation of electricity demand and supply as well as a domestic resources assessment. The option was the introduction of CANDU-PHWR through a license agreement with AECL Canada. The major factors in this choice have been the need of diversifying the energy resources, the improvement the national industry and the independence of foreign suppliers. Romanian Nuclear Power Program envisaged a large national participation in Cernavoda NPP completion, in the development of nuclear fuel cycle facilities and horizontal industry, in R and D and human resources. As consequence, important support was being given to development of industries involved in Nuclear Fuel Cycle and manufacturing of equipment and nuclear materials based on technology transfer, implementation of advanced design execution standards, QA procedures and current nuclear safety requirements at international level. Unit 1 of the first Romanian nuclear power plant, Cernavoda NPP with a final profile 5x700 Mw e, is now in operation and its production represents 10% of all national electricity production. There were also developed all stages of FRONT END of Nuclear Fuel Cycle as well as programs for spent fuel and waste management. Industrial facilities for uranian production, U 3 O 8 concentrate, UO 2 powder and CANDU fuel bundles, as well as heavy water plant, supply the required fuel and heavy water for Cernavoda NPP. The paper presents the Romanian activities in Nuclear Fuel Cycle and waste management fields. (authors)

A Threefold Assessment of the Romanian Economy’s Eco-efficiency

Directory of Open Access Journals (Sweden)

Viorel Niţă

2012-12-01

Full Text Available The present paper assesses the ecological sustainability of the Romanian economy from three different angles. The first two applications use the economy's energy and material consumption as proxy for its overall environmental impact. The third assessment approach is a qualitative and context-based one: the main obstacles to and opportunities for incorporating sustainability-competitiveness synergies into the Romanian industrial firms' management are identified. In the period 2000-2007, GDP growth was an important contributor to the Romanian economy's eco-efficiency levels, while the material and energy consumption remained constant or even increased. The predominance of competitive advantages based on low labour costs, high potential of increasing labour productivity, deficient environmental and industrial policies, and lack of awareness in both business and policy environment as to the beneficial role of resource productivity increase constitute significant obstacles to adopting competitive sustainability strategies. Fortunately, the relatively low levels of eco-efficiency and eco-innovation in industry offer in fact a wide scope of still unexploited win-win solutions. On the basis of the results, further research directions are sketched and several desirable public policy actions for enhancing the ecological sustainability of the Romanian economy are put forward.

International Nuclear Information System (INIS)

Varga, Bogdan Ovidiu

2013-01-01

Starting on the 24th of April, 2011, the Romanian government offered to subsidize all potential buyers of electric vehicles, both private and corporate, offering 25% off of the retail price up to 5000 euros with no pollution tax. The Romanian government encourages all governmental institutions to consider buying electric vehicles when deciding to change their existing vehicles stock. This decision is strictly related to the Romanian government's approval of a long-term Energy Strategy, building on the National Energy Strategy for the Medium Term. The government's strategy emphasizes increasing energy efficiency and boosting renewable energy use. The first electric vehicles distributed in the Romanian market are the Citroen-C-Zero, the Mitsubishi i-MiEV, the Renault Kangoo Z.E. and the Renault Fluence Z.E. The energy consumption of these vehicles was analyzed, considering the CO 2 generation characteristics of a Romanian electric power plant. -- Highlights: ► Tax and governmental support for electrical vehicles in Romania. ► Evaluate the CO 2 pollution of the electrical vehicles in Romania's case. ► Comprehensive understanding of the influence of primary energy source over the pollution of an electrical vehicle. ► Approach to decrees the pollution of the electrical vehicles.

Full Text Available Spatial databases are a new technology in the database systems which allow storing, retrieving and maintaining geospatial data. This paper describes the steps which we have followed to model, design and develop a spatial database for Romanian archaeological sites and their assemblies. The system analysis was made using the well known Entity-Relationship model; the system design included the conceptual, the external and the internal schemas design, and the system development meant developing the needed database objects and programs. The designed database allows users to load vector geospatial data about the archaeological sites in two distinct spatial reference systems WGS84 and STEREO70, temporal data about the historical periods and cultures, other descriptive data and documents as references to the archaeological objects.

Romanian nuclear fuel program

The paper presents and comments the policy adopted in Romania for the production of CANDU-6 nuclear fuel before and after 1990. The CANDU-6 nuclear fuel manufacturing started in Romania in December 1983. Neither AECL nor any Canadian nuclear fuel manufacturer were involved in the Romanian industrial nuclear fuel production before 1990. After January 1990, the new created Romanian Electricity Authority (RENEL) assumed the responsibility for the Romanian Nuclear Power Program. It was RENEL's decision to stop, in June 1990, the nuclear fuel production at the Institute for Nuclear Power Reactors (IRNE) Pitesti. This decision was justified by the Canadian specialists team findings, revealed during a general, but well enough technically founded analysis performed at IRNE in the spring of 1990. All fuel manufactured before June 1990 was quarantined as it was considered of suspect quality. By that time more than 31,000 fuel bundles had already been manufactured. This fuel was stored for subsequent assessment. The paper explains the reasons which provoked this decision. The paper also presents the strategy adopted by RENEL after 1990 regarding the Romanian Nuclear Fuel Program. After a complex program done by Romanian and Canadian partners, in November 1994, AECL issued a temporary certification for the Romanian nuclear fuel plant. During the demonstration manufacturing run, as an essential milestone for the qualification of the Romanian fuel supplier for CANDU-6 reactors, 202 fuel bundles were produced. Of these fuel bundles, 66 were part of the Cernavoda NGS Unit 1 first fuel load (the balance was supplied by Zircatec Precision Industries Inc. ZPI). The industrial nuclear fuel fabrication re-started in Romania in January 1995 under AECL's periodical monitoring. In December 1995, AECL issued a permanent certificate, stating the Romanian nuclear fuel plant as a qualified and authorised CANDU-6 fuel supplier. The re-loading of the Cernavoda NGS Unit 1 started in the middle

MOISTURE-BUFFERING CHARACTERISTICS OF BUILDING MATERIALS

2016-05-01

Full Text Available The humidity level of indoor air is an important factor influencing the air quality and energy consumption of buildings, as well as the durability of building components. Indoor humidity levels depend on several factors, such as moisture sources, air flow, and the adsorption/desorption properties of materials. The moisture-buffering characteristics of building materials that are in contact with indoor air may help moderate the variations of indoor humidity, especially in the summer and winter. In this study, the moisture adsorption/desorption properties of building materials were investigated experimentally and numerically. These properties can be used to characterize the ability of building materials to exchange moisture with the indoor environment. This study indicates that a building material surface resistivity was the main factor creating variations of moisture buffering.

Building activity has recently led to the deterioration of environment and has become unsustainable. Several strategies have been introduced in order to minimize consumption of energy and resulting CO2 emissions having their origin in the operational phase. But also other stages of Life Cycle should are important to identify the overall environmental impact of construction sector. In this paper 5 similar Slovak buildings (family houses) were analyzed in terms of environmental performance of building materials used for their structures. Evaluation included the weight of used materials, embodied energy and embodied CO2 and SO2 emissions. Analysis has proven that the selection of building materials is an important factor which influences the environmental profile. Findings of the case study indicated that materials like concrete, ceramic or thermal insulation materials based on polystyrene and mineral wool are ones with the most negative environmental impact.

The most effective building materials account for the highest growth not only in construction of residential and public buildings, but also other capital projects including roadways, bridges, drainage, communications and other engineering projects. Advancement in the technology of more efficient and ecologically responsible insulation materials have been a priority for safety, minimal maintenance and longevity of finished construction projects. The practical use of modern building materials such as insulation, sound reduction and low energy consumption are a benefit in cost and application compared to the use of outdated heavier and labor-intensive materials. The most efficient way for maximizing insolation and sound proofing should be done during the design stages of the project according to existing codes and regulations that are required by Western Government. All methods and materials that are used need to be optimized in order to reach a high durability and low operational and maintenance cost exceeding more than 50 years of the life of the building, whether it is for public, industrial or residential use. Western construction techniques and technologies need to be applied and adapted by the Russian Federation to insure the most productive successful methods are being implemented. The issues of efficient insulation materials are outlined in this article.

[German influences on Romanian medical terminology].

Răcilă, R G; Răileanu, Irena; Rusu, V

2008-01-01

The medical terminology plays a key part both in the study of medicine as well as in its practice. Moreover, understanding the medical terms is important not only for the doctor but also for the patients who want to learn more about their condition. For these reasons we believe that the study of medical terminology is one of great interest. The aim of our paper was to evaluate the German linguistic and medical influences on the evolution of the Romanian medical terminology. Since the Romanian-German cultural contacts date back to the 12th century we had reasons to believe that the number of German medical words in Romanian would be significant. To our surprise, the Romanian language has very few German words and even less medical terms of German origin. However, when we searched the list of diseases coined after famous medical personalities, we found out that 26 % of them bore the names of German doctors and scientists. Taken together this proves that the German medical school played an important role on the evolution of Romanian medicine despite the fact that the Romanian vocabulary was slightly influenced by the German language. We explain this fact on the structural differences between the Romanian and German languages, which make it hard for German loans to be integrated in the Romanian lexis. In conclusion we state that the German influence on the Romanian medical terminology is weak despite the important contribution of the German medical school to the development of medical education and healthcare in Romania.

Mrnustik, J.

1988-01-01

Within a study of the natural radioactivity of building materials, coefficients were determined of the emanation from selected materials and raw materials, such as porous concrete, bricks, marlite, quartzite, etc. Measurements were made of ground samples using Lucas scintillation chambers which give an accuracy of determination of the coefficient of about 10%. Specific radium activity was also determined for the samples. Tabulated is a comparison of the average specific activity of radium in concrete, power plant ash and porous concrete in Czechoslovakia and abroad. It is stated that monitoring the content of natural radionuclides in building materials is an indispensable part of the production process in the building industry, this with regard to the radiation protection of the population. This will be enhanced by the new Czechoslovak standard determining methods of measuring the content of natural radionuclides and the coefficient of radon emanation, and the subsequent evaluation of the properties of building materials.

Full Text Available The paper explores the tool of Competitive Intelligence (CI as an effective method of building one’s capability and focus and illustrates the benefits of gathering competitive intelligence by applying it on the top technology services firms in India. These results are then analysed in the light of the responses to the questionnaire administered to the selected three Romanian Offshore technology services providers. The study revolves around the key assumption that there is a set of factors common to all industry players whether in India or Romania, so it would be vital to collect information about how do these global competitors perceive their external environment and what strategies are they planning to adopt in order to grow in these competitive scenario. Given the growth targets set by these Romanian firms over the next five years and given the fact that there is no formal practice of gathering CI, the study recommends strategies for these Romanian players and builds a case for developing a Competitive Intelligence Plan by these firms in order to make the most of their capabilities and stay competitive.

Full Text Available Current economic and financial crisis appears to be unprecedented in the last half century.A massive loss of confidence, both in the business sector and the consumers, both responding byrestricting spending, is in full progress. The world's financial and economic crisis is largely the resultof greed, of unjust gain, of financial speculation, of tax evasion worldwide. We live in a world wherepeople are seeking more temporary material wealth than spiritual wealth of the Faith and eternal life,and in addition to more severe material poverty, we see spiritual poverty and weakening of faith, acooling brotherly love and a decrease in good deeds and philanthropy. In this situation of economicpolicy without ethics, when everything is uncertain and unpredictable, changeable, and deceitful, weneed to close to God, the steadfast and insurmountable, just and merciful, but also an increase inalertness, attention and financial prudence. Romanian Orthodox Church is in a enough favorableposition into the Romanian society to take a proactive process of anticipating social problems thattrouble present Romanian society (poverty, social exclusion, unemployment, migration, domesticviolence, school dropout, alcoholism, drug abuse, aging, social system and poor health, lack ofmotivation and educational perspectives, youth work and family, etc., which will ultimately lead todeveloping a comprehensive plan for promotion and social involvement that will play a decisive rolein solving social and spiritual needs of Romanians, present and future.

Full Text Available In this paper we investigated the sources of “Buy Romanian” attitude. Weformulated three constructs namely Buy Romanian, nationalism andinternationalism and we measured them by developing three scales. Thescales were included in a questionnaire that was administered to 110respondents. Performing statistical analysis, the results showed us that BuyRomanian is influenced by the general opinion toward the Romanianproducts and by nationalism orientation. There is no correlation among BuyRomanian and internationalism. These findings are useful because in orderto stimulate buying behavior of Romanian products by Romanian consumers,it is necessary to spot the deepest motivations.

Dragons in Slavic and Romanian Cultures

2013-06-01

Full Text Available Due to its geographical position, the Romanian ethnic territory is at the confluence of various languages, cultures and civilizations and the Romanian culture shares many features with the Slavic cultures because of the linguistic and cultural contact and the similar historical conditions under which they flourished. The issue of Slavic influence on Romanian culture has appealed to many researchers that have sought to explain the mystery of how a Romance culture survived in a territory surrounded by Slavs. Similar customs and folk representations circulated in both directions – from common Romanian to the Slavic languages and cultures and vice versa. Some motifs concerning the demons should demonstrate a broad area of common or similar representations in both types of cultures. This work will thus offer a new approach to the study of the Romanian-Slavic and Romanian-Balkan relationship and we hope a synthetic and unified vision of their common elements, and it will try to give some new ideas about an unresolved, debated, and contentious topic.

From Romanian to “Rumanol”: linguistic confusions in native Romanian spoken by children born in Spain

Lavinia Seiciuc

2014-06-01

Full Text Available After Romania joined the European Union in 2007, a massive wave of Romanian immigrants reached the Western countries in search for work, and the most significant migration took place in the Spanish kingdom. They were not the first Romanians to arrive in Spain, so they added their number to that of those who immigrated before, in the two decades after the fall of the Communist regime. Many Romanian children were born in Spain, so when they reached school age, they were at best bilingual; nevertheless, there are children who need to take Romanian classes in school, as they chose not to learn their native tongue at home. Our article analyzes the ways Spanish influence their pronunciation and orthography of Romanian, based on test papers and homework that demonstrate the level of confusion produced in these children by their bilingualism, with Castilian being their first choice of language.

Full Text Available Because the reduction in environmental impacts (EIs of buildings using life-cycle assessment (LCA has been emphasized as a practical strategy for the sustainable development of the construction industry, studies are required to analyze not only the operational environmental impacts (OEIs of buildings, but also the embodied environmental impacts (EEIs of building materials. This study aims to analyze the EEIs of Korean apartment buildings on the basis of major building materials as part of research with the goal of reducing the EIs of buildings. For this purpose, six types of building materials (ready-mixed concrete, reinforcement steel, concrete bricks, glass, insulation, and gypsum for apartment buildings were selected as major building materials, and their inputs per unit area according to the structure types and plans of apartment buildings were derived by analyzing the design and bills of materials of 443 apartment buildings constructed in South Korea. In addition, a life-cycle scenario including the production, construction, maintenance, and end-of-life stage was constructed for each major building material. The EEIs of the apartment buildings were quantitatively assessed by applying the life-cycle inventory database (LCI DB and the Korean life-cycle impact assessment (LCIA method based on damage-oriented modeling (KOLID, and the results were analyzed.

Optimal technical and economic strategy for retrofitting residential buildings in Romania

Căruțașiu Mihail-Bogdan

2017-07-01

Full Text Available The European Legislation is very strict regarding the importance of reducing the energy consumption in buildings sector. The importance of achieving nearly zero energy consumption levels for both new and existing buildings is also highlighted in each Members’ national legislation. Moreover, the high percentage of existing buildings across European Union, indicates that they need to be adequately approached in order to achieve the ambitious energy efficiency goals. This implies creating the optimal technical and financial retrofit strategies regarding minimizing the energy consumption without lowering the interior comfort levels. In Romania, there is no unitary strategy aiming to maximize the energy efficiency in buildings which also takes into consideration the financial part of the process. Moreover, there are no known national guidelines and strategies for buildings retrofit which takes into consideration a wide range of equipment. The Romanian Energy Efficiency Strategy presents few possibilities resulted from integrating renewable energy sources within typical Romanian buildings, while the Buildings Performance Institute Europe conducted a research regarding the potential of nearly Zero Energy Buildings implementation across Romanian territory. Both studies refer only to typical buildings and do not present a large perspective for retrofitting action, while the financial study is not properly presented. Thus, this paper develops a comprehensive financial study which could be used as guideline by stakeholders, in order to find the best technical solution for decreasing the final energy consumption in Romanian residential buildings. Using the RETScreen software and its economical features, there were developed several energy efficiency solutions, and by analyzing the financial benefits implied, the best solution was chosen. By adopting the solutions presented within this feasibility study, the energy consumption of buildings should be

Rusu Liviu Dumitru

2015-07-01

Full Text Available Globalization has deeply turned the macroeconomic environment as well as the behaviour of organizations on the global market. Increasingly fierce competition on this market has contributed to the emergence and crystallization of the euro management which was called upon to respond to this challenge. It is closely related to organizational culture and developed on the basis of the integration of markets and economies which led to the appearance, in the management area, of a methods ’ concentration, management techniques and methodologies specific to the European countries. As a part of the European management, the Romanian management involves the formulation of some specific traits, defining features, detached from its approach both on processes and management functions as well as on the components of the management system. This approach results from the organization's system feature called "management system". The objectives of this work consist in the formulation of some relevant answers to questions like: "Do the Romanian Managers have a certain conception in terms of functions of the management processes?"; "Was there outlined a specific content for each of the five managerial functions?"; "Is the content of the management components /subsystems already patterned?". As a methodology, from the answer to these questions , there will be taken some conclusions on the "Romanian management" from the theoretical-methodological point of view as a first stage and, on the second stage, as a pragmatic approach on the Romanian organizations and generally within the business environment in Romania. As a result, in the end we present the defining elements of the "Romanian management pattern", to the extent that we come to the conclusion that one can speak of such a model and which are the common and distinct traits as against the European management.

2015-09-01

Full Text Available This paper analyses the determinants of Romanian emigration considering two perspectives: first, the perspective of business environment and labour market and, second, the perspective of social and economic conditions. The analysis uses data from National Statistical Institute and Romanian Register of Commerce for all 42 counties of Romania for the year 2011 and consists of three linear regression models whose dependent variable was the total number of Romanian emigrants declared at 2011 Romanian Census. Results have shown that international migration is strongly correlated with national labour policy. The fact that newly created enterprises have a positive influence on migration show that Romanian business environment is not able to offer competitive salaries and/or working conditions.

Understanding the earthquake phenomena and their effects is an important step toward the education of population and aims to raise the awareness about the earthquake risk and possible mitigation actions. In this sense, The Romanian Educational Seismic Network project represents an efficient communication tool, allowing teaching and learning about the earthquakes and seismic wave impact through experimental practices and educational activities. The seismic network consist of nine SEP seismometers installed in high-schools from the most important seismic areas (Vrancea, Banat, Făgăraş, Dobrogea), vulnerable cities (Bucharest, Iasi) or high populated places (Cluj, Sibiu, Timisoara, Zalău) and is coordinated by the National Institute of Earth Physics from Bucharest. Once installed, the seismic network is the starting point of activities for students through an e-learning platform. Some objectives are aimed: - To train students and teachers how to make analysis and interpretation of seismological data; - To make science more interesting for students; - To improve the participation rates in physical sciences for students; - To raise awareness of geoscience as a scientific discipline for pre-university students; - To promote the installation and effective use of educational seismographs and seismic data; - To reinforce and develop relationships between participating schools and research institutes; - To create an earthquake database this will be used by students and teachers for educational purposes. Different types of practical activities using educational seismometer, designed by researchers for students, are described in educational materials and in the web platform project. Also we encourage the teachers from the participating schools to share their experiences and produce new didactic tools for the classroom. This collaborative work could illustrate the conjugated efforts of researchers and teachers for a better education and awareness of the risk culture

Some reflections on Romanian translation studies

Full Text Available In this paper, I decided to examine two “verdicts” on the specificity (or the lack of specificity of Romanian translation studies in order to define and explain the present situation in this field: one given in the Encyclopedia of Translation Studies, the other in a book on “Romanian translation ideas and meta-ideas”. I believe that the current situation justifies the following hypothesis: the current specific of translation theories in the Romanian space is entailed by the existence of two circuits. The first is academic and international, aiming at including the Romanian research in European directions, by assimilating them more or less. The second is a national circuit—where the positions expressed within the first circuit penetrate indirectly, through “central” languages—and it manifests itself as selective and elective affinities between the two; their interaction is sporadic and it occurs mainly through other languages, not through an interiorization process related to the language of the Romanian source space.

Mărăști Village, 1918, a village on the front line of the First World War, the place where General Mackensen and General Averescu met face to face for 12 days. After the 12 days of heavy fighting at an altitude of 536 meters, the Romanians won the battle, but they lost 4800 people and the village was destroyed. The village was rehabilitated due to Mărăști Society; whose objective was to rebuild it as a “historical village in the Romanian style”. The place was in a building site for 6 years. A number of 73 houses were rehabilitated and 20 new houses, a church and a school were erected. The village was provided with a water supply system and an electricity grid with diesel-generators. All this was designed in the Neo-Romanian style by 6 architects. In a short period and on a large territory, the terrible consequences of the war were changed into a reconstruction and modernization theme, from the infrastructure in general to the dwellings in particular. It was a tremendous effort because of the isolated position of the village, which required an impressive logistic support for those times. The new architectural products were designed in the style that was already considered the Neo-Romania style in the 1910-1920 decade. The village is important because it was modernized from the urban point of view. It was a completely new manner characteristic of the urban development in an area where the last Middle Ages peasant upheaval took place in 1907. In the Romanian context, the execution is unique in dimension, scale and theme. At the International level, it is considered a very precise and rare architectural intervention.

2012-07-01

Full Text Available The paper aims at analyzing the dynamics of in Romanian higher education graduates in the 2006-2010 period, both in Romania and by the Romanian development regions. After highlighting the importance of human capital and its education, the paper analyzes the dynamics of Romanian higher education graduates in the targeted period, at both of the above-mentioned levels. The conclusions reveal that, during the analysed period: 2006-2010, the number of female, and, respectively, male higher education graduates, as well as the total number of higher education graduates, continuously increased in the 2006-2010 period at the whole country level and registered an increase trend, as well, by the eight development regions of Romania in the 2006-2010 period, with very few exceptions in some years of the period, in some of the the eight development regions of Romania. Therefore, the Romanian higher education system must correlate the graduates number with the number of work places in the Romanian economy, and take into account the necessities imposed by the participation at international competition.

Full Text Available This is a comment on the type of democracy in Romania, as illiberal democracy. Given the Romanian democratization process, we can hope that, in the future, all populisms and politicization will cease, and a true liberal and constitutional democracy will be installed, which will not be a „Romanian democracy” as Paul Wolfowitz suggested to be exported in Iraq. The question is whether it is good or not to „export” such a political model. „Romanian democracy” could be an exporting model only as an alternative to dictatorship and under the assumption that it will be adjusted in time, under the external pressure.

Full Text Available The remittances of international migrants are particularly important for Romania as one of the top European emigration countries and an important remittance recipient country as well. Responding to the need to better understand the determinants of remittances, our paper examines the significance of selected economic, social and demographic factors that impact on the remittance behaviour of Romanian international migrants, as characterized by the propensity to remit and the amount remitted. The present work builds on a new database of 1514 Romanian migrants from 52 destination countries, resulting from our 2010 online survey. One of the main findings is the fact that the remittances are strongly affected by migrant’s income, return intention and presence of the spouse in the destination country.

The field of building environmental assessment tools has become a popular research area over the past decade. However, how the service life of a building affects the results of the environmental assessment of a building has not been emphasised previously. The aim of this study is to analyse how different structural solutions and building materials affect the results of the environmental assessment of a whole building over the building's life cycle. Furthermore, how the length of the building's service life affects the results is analysed. The environmental assessments of 78 single-family houses were calculated for this study. The buildings have different wall insulations, claddings, window frames, and roof materials, and the length of the service life varies from 60 years up to 160 years. The current situation and the future of the environmental assessment of buildings are discussed. In addition, topics for further research are suggested; for example, how workmanship affects the service life and the environmental impact of a building should be studied

Predicting the indoor air relative humidity evolution is of great importance to evaluate people thermal comfort, perceived air quality and energy consumption. In building environments, porous materials of the envelope and furniture act on the indoor air humidity by reducing its variations. Solving the physical processes involved inside the porous materials requires the knowledge of the material hygrothermal properties that needs multiple and, for some of them, time-consuming experimental procedures. Recently, both the NORDTEST Project and Japanese Industrial Standard described a new Moisture Buffer Capacity index that accounts for surrounding air vapor concentration variation. The Moisture Buffer Value (MBV) indicates the amount of water vapor that is transported in or out of a material, during a certain period of time, when the vapor concentration of the surrounding air varies. The MBV evaluation requires only one experimental procedure and its value permits a direct comparison of the building materials moisture performance. However, two limitations can be distinguished: first, no relation between the MBV and the usual material hygrothermal properties has been clearly identified and second, no model has been proposed to actually use the MBV in building simulation. The present study aims to solve these two problems. First, the MBV fundamentals are introduced and discussed; followed by its relation with the usual material properties. Then, a lumped model for building simulation, whose parameters can be determined from the MBV experimental procedure, is described. To finish, examples of the use of this MBV-based lumped model for moisture prediction in buildings are presented. (author)

2017-09-01

Full Text Available The analysis of a rich old Romanian corpus shows that the ‘pluralization’ of mass and abstract nouns is extremely frequent in old Romanian. The semantic effects of pluralization are similar for mass and abstract nouns, consisting in the creation of denotative and/or connotative semantic variants. Of the plural endings, –uri is specialized for the pluralization of mass nouns in Daco-Romanian. The evolution of the ending –uri illustrates the specific process by which a grammatical (plural morpheme is converted into a lexical morpheme (the so-called ‘lexical plurals’. ‘Lexical plurals’ have isolated occurrences in other Romance languages, but they have not reached the spread and regularity they display in Romanian.

Full Text Available The traditional Romanian costume such as the entire popular art (architecture, woodcarvins, pottery etc. was born and lasted in our country since ancient times. Closely related to human existence, the traditional costume reflected over the years as reflected nowadays, the mentality and artistic conception of the people. Today the traditional Romanian costume became an inspiration source to the wholesale fashion production industry designers, both Romanian and international. Although the contemporary designers are working in accordance with a vision, using a wide area of styles, methods and current technology, they usually return to traditional techniques and ethnic folklore motifs, which converts and resize them, integrating them in their contemporary space. Adrian Oianu is a very appreciated Romanian designer who launched two collections inspired by his native’s country traditional costumes: “Suflecata pan’ la brau” (“Turned up ‘til the belt” and “Bucurie” (“Joy”. Dorin Negrau had as inspiration for his “Lost” collection the traditional costume from the Bihor region. Yves Saint Laurent had a collection inspired by the Romanian traditional flax blouses called “La blouse roumaine”. The paper presents the traditional Romanian values throw fashion collections. The research activity will create innovative concepts to support the garment industry in order to develop their own brand and to bring the design activities in Romania at an international level. The research was conducted during the initial stage of a project, financed through national founds, consisting in a documentary study on ethnographic characteristics of the popular costume from different regions of the country.

2000-01-01

In order to stop the global warmth due to the CO2 concentration, the energy use should be decreased. The investment of building construction industry in Japan is about 20 percent of GDP. This fraction is much higher than in most developed countries. That results the Japanese building construction industry including residential use consumes about one third of all energy and resources of the entire industrial sectors. In order to save energy as well as resource, the recycle of the building materials should be urgent to be carried out. In this paper, we focus on the potential energy savings with a simple calculated method when the building materials or products are manufactured from recycled materials. We examined three kinds of residential buildings with different construction techniques and estimated the decreased amount of energy consumption and resources resulting from use of recycled materials. The results have shown for most building materials, the energy consumption needed to remake housing materials from recycled materials is lower than that to make new housing materials. The energy consumption of building materials in all case-study housing can be saved by at least 10 percent. At the same time, the resource, measured by mass of building materials (kg) can be decreased by over 50 percent

2017-12-01

Phase change material (PCM) is widely known as latent heat storage. A comprehensive study is carried out to investigate the effect of PCM on heat transfer rate of building materials. Paraffin is used as PCM along with different conventional building materials to investigate the heat transfer rate from the heated region to the cold region. PCM is placed along with the three different types of building materials like plaster which is well know building material in urban areas and wood and straw which are commonly used in rural areas for roofing as well as wall panel material and investigated the heat transfer rate. An experimental setup was constructed with number of rectangular shape aluminum detachable casing (as cavity) and placed side by side. Series of rectangular cavity filled with convent ional building materials and PCM and these were placed in between two chambers filled with water at different temperature. Building materials and PCM were placed in different cavities with different combinations and investigated the heat transfer rate. The results show that using the PCM along with other building materials can be used to maintain lower temperature at the inner wall and chamber of the cold region. Moreover, the placement or orientation of the building materials and PCM make significant contribution to heat transfer rate from the heated zone to the cold zone.

Full Text Available This quantitative study examines the correlations between humor, loneliness, gender and aging by presenting the results from a sample of eighty-three older Romanian adults, aged sixty and above. The first section of the paper is a comprehensive review of the social-psychological literature on aging, gender and humor. The second section assesses the findings generated from a study that uses the Multidimensional Sense of Humor Scale (Thorson & Powell, 1993 and the Social and Emotional Loneliness Scale for Adults – short version, (diTomaso, Brannen & Best, 2004. Building on Robert Weiss’s (1973 reflections on the differences between feelings of loneliness because of social isolation or emotional isolation, the research findings nuance –and in some cases challenge several assumptions on gender, age, and emotional and social loneliness. The findings also point to the correlation between feelings of social loneliness and the use of humor in interpersonal communications. The data collected suggests that while Romanian men may value the use of humor more than women when self-reporting, that older Romanian women tend to use humor in interpersonal situations and that there is a significant correlation between the use of this type of humor and a reduced sense of social loneliness.

Full Text Available The study analyses the media coverage practices concerning the “new diaspora”– the migration of the Romanian workforce in the countries of the European Union. Themain research question relates to how the media builds the image of the migrant, aswell as of the emerging forms in which the diaspora presents itself: is the diaspora a“distant” phenomenon (eventually recovered within a policy-media agenda or, on thecontrary, does the press propose varied and nuanced images of the migrant condition,approaching this theme as a public issue? In other words, what forms of “moraldistance” does the media build with respect to the Romanians who work abroad? Byapplying content analysis combined with discourse analysis with respect to two nationaldaily newspapers, the study shows that the press “defines” the diaspora as an abstractreality, in a sketchy presentation of idealized characters vs. negative characters. Assuch, the media establishes an imagery of compassion and benevolent attention – anexterior reality of the national public. The media discourse does not point out theparticularities of the diasporic experience in the context of the various types of mobility.

Full Text Available This paper analyzes the relationship between permanent monuments and temporary art projects, as temporality is one of the strategies employed by Romanian artists to counterbalance the support that the Romanian state has shown only towards monuments and memorials dedicated to affirming its value. The complex nature of public art requires a careful consideration of the different dimensions this practice employs, and for that the Western debate on this matter can be a reference point in understanding Romanian public art. We will be looking at possible aspects of the functions of these two main directions in Romanian public art, as they stand methodically one in opposition to the other, in connection with the texts of Piotr Piotrowski (Art and Democracy in Post-communist Europe, 2012 and Boris Groys (Art Power, 2008.

Rapeanu, S.N.; Bujor, A.; Comsa, O.

1998-01-01

The need of diversifying the energy sources, independence from foreign supplies and modernization of economy have constituted the major factors in implementation of nuclear energy in Romania. The choice of the heavy water reactor CANDU-600 was made on grounds of advanced safety features, proven efficient economic operation as well as on the technologic feasibility for manufacturing of components, equipment, instrumentation, heavy water and natural uranium fuel in Romania. Unlike turn-key acquisition approaches, the Romanian option provided an active national participation in construction the Cernavoda NPP. As consequence, important support was being given to development of the industries involved in the nuclear fuel cycle, manufacturing of equipment and nuclear materials, construction-montage, engineering, consulting, services, etc. This was done based on technology transfer, implementation of advanced design and execution standards, quality assurance procedures and modern nuclear safety requirements at international level. The efforts materialized in an important national participation in the construction of the Cernavoda NPP and all related programs are successful. Now, Romanian firms are also involved in supplying components, equipment and services to NPP's in other eastern and central Europeans countries. The paper presents the achievements of the Romanian economy in this field and the effort of the Romanian companies on the small and medium power reactors market. Lists with main R and D institutes, nuclear fuel cycle facilities as well as potential equipment suppliers are attached. (author)

Previous studies have shown that the natural radioactivity contained in building materials have significantly influenced the dose rates in dwelling. Exposure to natural radiation in building has been of concerned since almost 80 % of our daily live are spend indoor. Thus, the aim of the study is to assess the radiological risk associated by natural radioactivity in soil based building materials to dwellers. A total of 13 Portland cement, 46 sand and 43 gravel samples obtained from manufacturers or bought directly from local hardware stores in Peninsular of Malaysia were analysed for their radioactivity concentrations. The activity concentrations of 226 Ra, 232 Th and 40 K in the studied building materials samples were found to be in the range of 3.7-359.3, 2.0-370.8 and 10.3-1,949.5 Bq kg -1 respectively. The annual radiation dose rates (μSv year -1 ) received by dwellers were evaluated for 1 to 50 years of exposure using Resrad-Build Computer Code based on the activity concentration of 226 Ra, 232 Th and 40 K found in the studied building material samples. The rooms modelling were based on the changing parameters of concrete wall thickness and the room dimensions. The annual radiation dose rates to dwellers were found to increase annually over a period of 50 years. The concrete thicknesses were found to have significantly influenced the dose rates in building. The self-absorption occurred when the concrete thickness was thicker than 0.4 m. Results of this study shows that the dose rates received by the dwellers of the building are proportional to the size of the room. In general the study concludes that concrete building materials; Portland cements, sands, and gravels in Peninsular of Malaysia does not pose radiological hazard to the building dwellers. (author)

Building materials can cause significant gamma dose indoors, due to their natural radioactivity content. The knowledge of the natural radioactivity level of building materials is important for determination of population exposure, as most people spend 80-90% of their time indoors furthermore, it is useful in setting the standards and national guidelines for the use and management of these materials. The concentrations of natural radionuclides in building materials vary depending on the local geological and geographical conditions as well as geochemical characteristics of those materials. The aim of the study is to determine levels of natural radionuclide in the commonly used building materials in Hyderabad, India

Forced Labor during the Romanian Holocaust

Mihai Chioveanu

2012-10-01

Full Text Available My paper aims to retrieve and present in general lines one aspect of the Romanian Holocaust that was since recently ignored by most scholars in the field, namely the forced labor of the Jewish population. Part of the deliberate anti-Jewish policy of the Antonescu government, the issue of forced labor is relevant as it completes the picture of the Holocaust in Romania, at the same time indicating the border between the Romanian apartheid society and the Romanian genocidal state. The paper thus points at the necessity for the scholars to continue their research in the field of holocaust studies at large, a topic that is far from exhausting its resources and significance.

2012-12-01

Natural radioactivity due to (226)Ra, (232)Th and (40)K in the common building materials collected from Baotou city of Inner Mongolia, China was measured using gamma-ray spectrometry. The radiation hazard of the studied building materials was estimated by the radium equivalent activity (Ra(eq)), internal hazard index (H(in)) and annual effective dose (AED). The concentrations of the natural radionuclides and Ra(eq) in the studied samples were compared with the corresponding results of other countries. The Ra(eq) values of the building materials are below the internationally accepted values (370 Bq kg(-1)). The values of H(in) in all studied building materials are less than unity. The AEDs of all measured building materials are at an acceptable level.

Romanian nuclear fuel program: past, present and future

The paper presents and comments the policy adopted in Romania for the production of CANDU-6 nuclear fuel before and after 1990. In this paper the word 'past' refers to the period before 1990 and 'present' to the 1990-1997 period. The CANDU-6 nuclear fuel manufacturing started in Romania in December 1983. Neither AECL nor any Canadian nuclear fuel manufacturer were involved in the Romanian industrial nuclear fuel production before 1990. After January 1990, the new created Romanian Electricity Authority (RENEL) assumed the responsibility for the Romanian Nuclear Power Program. It was RENEL's decision to stop, in June 1990, the nuclear fuel production at the Institute for Nuclear Power Reactors (IRNE) Pitesti. This decision was justified by the Canadian specialists team findings, revealed during a general, but well enough technically founded analysis performed at IRNE in the spring of 1990. All fuel manufactured before June 1990 was quarantined as it was considered of suspect quality. By that time more than 31,000 fuel bundles had already been manufactured. This fuel was stored for subsequent assessment. The paper explains the reasons which provoked this decision. The paper also presents the strategy adopted by RENEL after 1990 regarding the Romanian Nuclear Fuel Program. After a complex program done by Romanian and Canadian partners, in November 1994, AECL issued a temporary certification for the Romanian nuclear fuel plant. During the demonstration manufacturing run, as an essential milestone for the qualification of the Romanian fuel supplier for CANDU-6 reactors, 202 fuel bundles were produced. Of these fuel bundles, 66 were part of the Cernavoda NGS Unit 1 first fuel load (the balance was supplied by Zircatec Precision Industries Inc. - ZPI). The industrial nuclear fuel fabrication re-started in Romania in January 1995 under AECL's periodical monitoring. In December 1995, AECL issued a permanent certificate, stating the Romanian nuclear fuel plant as a qualified

In 1980, Ministry of Building and Building Materials Industry, the Central Laboratory for Radiological Protection (abbreviated as CLRP), Ministry of Health and Social Welfare have agreed to issue the compulsory regulation of performing the validation of investigations of building raw and materials. Methods of measurement, apparatus and method of evaluation of results of the investigations have been recommended for the whole country. The following two criteria of usefulness of a building material for housing and public building have been accepted, f 1 = 0.00027 S K + 0.0027 S Ra0 .0043 S Th ≤ 1 (this one limit exposition of the whole body to gamma radiation); f 2 = S Ra ≤ 185 Bq/kg (this one limits exposition of lung epithelium to progeny of radon 222 Rn exhaled from the building walls). The CLRP and Institute of Building Technology supervise over correctness (agreement with the regulations) of operation of laboratories in Departments of Building Industry and Energy, organize training of the personnel and collect results of the measurements. From 1980 till 1991, results of measurements of 6550 samples from 550 localities were collected in computer data base organized in CLRP. In this paper, results of examination of selected groups of building raw and materials have been presented. Annual average values of the qualification coefficients f 1 and f 2 have been also analyzed. (author). 7 refs, 13 figs, 2 tabs

We have investigated the HLA-class I and class II polymorphism in a population of 83 Romanians using conventional serology together with PCR amplification and oligonucleotide typing of HLA-class II genes. Romanians show a higher frequency of HLA-A11, B13, B18, B37, B39, B51 and DR2 than other European populations. HLA-DRB1*1501 and 1601 account for the high frequency of the serologic specificity DR2. In Romanians, HLA-DR2 is in linkage disequilibrium with HLA-B18 and HLA-Bw52 rather than with HLA-B7 as in the case in other Europeans. Unexpected HLA-DR2 haplotypes include HLA-DRB1*1502, DQA1*0102, DQB1*0601; HLA-DRB1*1602, DQA1*0102, DQB1*0502. Other unusual haplotypes include HLA-DRB1*0405, DQA1*03, DQB1*0302; HLA-DRB1*1305, DQA1*0103, DQB1*0603; and HLA-DRB1*1405, DQA1*0101, DQB1*05032. Analysis of the genetic distance between Romanians and other Europeans who have been studied serologically are consistent with the hypothesis that Romanians descend from Roman ancestors who colonized Dacia between the 1st century B.C. and 1st century A.D.

The need of diversifying the energy sources, independence from foreign supplies and modernization of economy have constituted the major factors in implementation of nuclear energy in Romania. The choice of the heavy water reactor CANDU-600 was made on grounds of advanced safety features, proven efficient economic operation as well as on the technologic feasibility for manufacturing of components, equipment, instrumentation, heavy water and natural uranium fuel in Romania. Unlike turn-key acquisition approaches, the Romanian option provided an active national participation in construction the Cernavoda NPP. As consequence, important support was being given to development of the industries involved in the nuclear fuel cycle, manufacturing of equipment and nuclear materials, construction-montage, engineering, consulting, services, etc. This was done based on technology transfer, implementation of advanced design and execution standards, quality assurance procedures and modern nuclear safety requirements at international level. The efforts materialized in an important national participation in the construction of the Cernavoda NPP and all related programs are successful. Now, Romanian firms are also involved in supplying components, equipment and services to NPP`s in other eastern and central Europeans countries. The paper presents the achievements of the Romanian economy in this field and the effort of the Romanian companies on the small and medium power reactors market.

Parameters for Building Materials Specifications in Lagos, Nigeria

Directory of Open Access Journals (Sweden)

Clement Oluwole Folorunso

2013-07-01

Full Text Available The responsibility of specifying materials for building construction purposes within Nigeria rests on the architects. Understanding the appropriate parameters for specifying building materials that could lead to immense financial proportion is required from the architects. The level of understanding and knowledge of architects is germane to the optimum performance of buildings throughout their life cycle. The methodology applied for this research involved the administration of a structured questionnaire on professional architects within the study area to determine the basis of their decision on the materials they specify or chose for building finishes. The parameters used to measure the specification of materials for finishes are client’s choice, cost, climatic compliance, and maintenance demand of materials. Findings show that the maintenance demand of materials is the most important factor that determines the specification of materials irrespective of the choice of client and climate. However, cost occupies a prominent role in the decision process. It also shows that most architects are not fully aware about the role of climate in determining the life cycle of materials in tropical environments. The compliance of materials to ever-changing climate does not constitute a major factor in the specification of materials in the area.

Full Text Available Romanian youth migration is an increasing phenomenon, due to subjective and objective factors as economical reasons, professional carrer and increasingly more international competition for talent. In these circumstances, the present article aims to evaluate determinant factors that contribute to the decision of Romanian graduates to return national labour market. We sustain that young Romanians consider carefully and hardly decide their professional future. A particular attention is given to their personal reasons and motivations as well as family and friends network. For designing returning factors we present the results of a questionnaire survey, asking young pupils and students about their future educational way and personal reasons underlying the decision to study in a foreign country and taking into consideration the returning decision. As far international student migration is seen as a first step to migration for work, our work desires to fight for returning home of Romanian well-educated graduates.

Gustitus, D.A.; Blaisdell, P.M.

1996-01-01

Environmental hazards in buildings can be found in the air, on exposed surfaces, or hidden in roofs, walls, and systems. They can exist in buildings in solid, liquid, and gaseous states. A sound methodology for investigating the presence of environmental hazards in buildings should include several components. The first step in planning an investigation of environmental hazards in buildings is to ascertain why the investigation is to be performed. Research should be performed to review available documentation on the building. Next, a visual inspection of the building should be performed to identify and document existing conditions, and all suspect materials containing environmental hazards. Lastly, samples of suspect materials should be collected for testing. It is important to sample appropriate materials, based on the information obtained during the previous steps of the investigation. It is also important to collect the samples using standard procedures. Pollutants of concern include asbestos, lead, PCBs, and radon

PIXE analysis of trace and other mineral elements in Romanian dental composites

International Nuclear Information System (INIS)

Preoteasa, E. A.; Iordan, Andreea; Harangus, Livia; Ciortea, C.; Moldovan, Maria

2002-01-01

Dental composites made of silicates and oxides particles embedded in an organic polymer, show a dynamic evolution but are rather expensive. Recently, the Romanian biomaterial 'Restacril' offered a low-cost alternative. Because the durability of the composite dental fillings depends both on the main chemical composition and on the impurities that may influence the inorganic particles' properties and thus modifying the bio material clinical behaviour, the elemental analysis of the material is necessary for improving its quality. Particle-induced X-ray emission (PIXE), a sensitive method for multielemental trace detection widely used in biomedical applications, allowed us to evidence 21 mineral elements with Z > 14 in some commercial dental composites. Here we evaluate the performances of PIXE for the control of dental composites by carrying out qualitative analysis of three Romanian biomaterials. PIXE measurements on thick composite samples with a flat surface were done with 3 MeV protons at the NIPNE-HH (Horia Hulubei National Institute for Physics and Nuclear Engineering) tandem accelerator, using a hyper-pure Ge detector, 30 mm thick Al absorber foil and integration of beam current. Up to 21 elements with Z > 19 were detected: K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Ga, Sr, Zr, Nb, Ru, Ag, Ba, Yb, Nd, Hf, Au, As and Pb. The orders of magnitude of relative concentrations were evaluated using X-ray yields obtained for another light element thick composite target. The Romanian composites have specific and diverse compositions, containing a great number of minor and trace elements, many of whom are impurities. Use of higher purity raw materials is suggested to reduce the latter and improve the materials' quality. Refinement of X-ray yields by better matching matrixes calculations and use of concentration standards are proposed for quantitative PIXE analysis of the dental composites. (authors)

The TV broadcast discusses problems of the modernization of the Romanian astronomical infrastructure, the worst in Eastern Europe. It presents the TELEROM project which proposed to establish a new EU-funded robotic 1,3 m telescope, a project finally rejected by the Astronomical Institute of the Romanian Academy mainly due to the incompetence of the director of this Institute, Dr. Vasile Mioc. It is mentioned that this was the second very promising project failed under the same director, after the project ASTEROS in value of 15 million Euro to establish two modern telescopes was also lost in the recent years. The total cost of the TELEROM project was 1,5 million Euro, according to the agreement with the EU foundation for Regional Development (director Hanns Ruder Institut für Theoretische Astrophysik, Universität Tübingen, Germany - the TELEROM auto-dimissed project director). The facilities from this implementation were very promising in observations of Solar system objects (asteroids, near Earth asteroids, comets), few hundred millions of faint stars, quasars, exoplanets and galaxies. Initially, the director Vasile Mioc and the governing body of the Romanian Astronomical Institute intended to place the telescope in Romania in very bad astroclimatic conditions, namely in the old Feleac observatory, very close to the very highly polluted and quite clouded city of Cluj-Napoca. Many opposite considerations (Dr. Marian Doru Suran from Bucharest, many Romanian astronomers from the Diaspora and a group of 68 astronomers, professors, public outreach people and students from Romania and Diaspora supporting TELEROM) were totally disregarded! Due to refuse to place the telescope in very good astroclimatic conditions (in Canary Islands or Chile) and also due to the impossibility to establish a decent national astronomical observatory in Romania by the direction of the Institute in agreement with the State body of Romania ("Academia Romana" and "Autoritatea Nationala pentru

Full Text Available Introduction: Presently, the scientists recognize the health benefits of food fibers in the menu and also plant food sources are at high interest both for general population and food companies. The food companies are responsible for a clear nutrition labelling that will assist consumers to make informed and healthy choices and health providers has to inform the population about the benefits of fibers. The aim of our study was to evaluate the Romanian knowledge and attitudes regarding dietary fibers from food products. Materials and methods: We made a qualitative survey based on a questionnaire applied in 2015, over a period of 6 months, over 670 Romanian consumers. It was focused on testing the attitudes and knowledge towards ingestion of foods rich in fibers. For all data analysis we used the software SPSS, from IBM Inc. Results and Discussions: Our results showed that the knowledge about dietary fibers and also the ingestion of food products rich in fibers were low, and most of the subjects didn’t have any interest to read the nutritional information from food labels related to fibers. The female participants ate more whole grains and fruits than males and pay more attention to food labelling, the Romanian people prefer to stay and eat home than at restaurants especially in rural areas, and the knowledge about fibers benefits was significantly related to education and urban location. Conclusion: We underline the needs for more efficient community interventions and proper information about the importance of dietary fibers for our health and also to improve and disseminate our nutritional standards and diet recommendation among population.

Pál Enikő

2015-03-01

Full Text Available Translation has always been important for religion as a way of preaching God's word. The first Romanian translations of religious texts, including the first (although incomplete translation of the Bible, date from the sixteenth century. In this early period of Romanian writing, Romanian translators encountered several problems in conveying the meaning of these texts of a great complexity. Some of the difficulties were due to the source texts available in the epoch, others to the ideal of literal translation, to the principle of legitimacy or to the relatively poor development of Romanian language which limited the translators' options. The present study focuses on the causes and purposes for which lexical items of Hungarian origin interweave old Romanian translations. In this epoch, Hungarian influence was favoured by a complex of political, legal, administrative and socioculturel factors, sometimes even forced by these circumstances. On the one hand, given the premises of vivid contacts between Romanians and Hungarians in the regions where the old Romanian translations (or their originals can be located, a number of Hungarian loanwords of folk origin penetrated these texts. On the other hand, when using Hungarian sources, translators have imported useful source language caiques and loanwords, which have enriched Romanian language.

Full Text Available This paper seeks to discuss the image that the media build around the phenomenon of migration in present-day Romanian society. I rely on a content analysis of newspaper articles on migration in order to explore layers of knowledge (understood as evidence which forms the basis of the representation about an issue by identifying specific elements in each and every piece of news, such as: the current state of migration, the demographic profile of the migrant, geographical location, the orientation of the newspaper, the situation of migrants, the causes and effects of this phenomenon, and the policies implemented in the communities of origin and destination, respectively. All these elements are examined along the lines of emigration and immigration in order to reconstruct strategies of framing external migration within the journalistic discourse, and to identify the information which constitutes a reference point in shaping the attribute agenda on this topic. The discussion relies on the analysis of 473 articles in Romanian newspapers, published between 2007 and 2009, using as a sampling frame the archive of articles available on the website www.ziare.com.

TRENDS IN ROMANIAN TOURISM

Full Text Available Tourism is an industry of the future, having the potential to provide significant revenues, and an industry of 'beauty', because it will protect, preserve and contribute to arranging the environment affected by other human activities. This is why it is very important to know the evolution of this underdeveloped field in our country. This paper is intended as a study on current trends in Romanian tourism without any claim of being an exhaustive research on the industry, describing the main indices of tourist traffic and their influence on Romanian tourism. Nowadays, we witness three main trends in Romanian tourism: sustainability, ecotourism and the increasing presence of cultural tourism. Ecotourism, as a form of tourism, has emerged from people's need to withdraw in nature, to visit and learn about the natural areas which have or have not a national or international protection status. Cultural tourism appears as a type of tourism clearly differentiated from other forms or types of tourism, particularly through motivation. It can be defined as a form of tourist mobility whose primary goal is broadening the horizon of knowledge by uncovering its architectural and artistic heritage and the areas in which it originates. Sustainability for tourism, as for other industries, has three independent aspects: economic, socio-cultural and environmental. Sustainability implies permanence, which means that sustainable tourism requires the optimal use of resources, minimizing the negative economic, socio-cultural and ecological impact, maximizing the benefits upon local communities, national economies and conservation of nature. Regarding statistical data, in what quantity is concerned, there is an increase in Romanian tourism, but in what quality is concerned there is a setback for tourism in the last years. This aspect should make public authorities take concern in improving the infrastructure and the quality of the touristical activity and in diversifying

Full Text Available The Romanian healthcare system is facing constant challenges to produce high quality care with low costs. Objectives The paper aims to analyze the efficiency of the Romanian healthcare system in terms of resources allocation. The evaluation and the dimension of healthcare system efficiency are important for identifying a balance between the resources required and the health outcomes. Prior Work Previous studies describe the Romanian healthcare system as a system in transition. This study focuses on the relationship between the inputs and outputs of the system. Approach In order to assess the efficiency of the Romanian healthcare system we use Data Envelopment Analysis approach. Both input and output healthcare indicators are observed for the period 1999-2010 and the years when healthcare inputs have been used efficiently are identified. Results The results show that human, financial, and technological resources have been used at maximum capacity in 1999, 2003, 2004, 2007 and 2010. Implications Though efficiency is defined differently by diverse stakeholders, healthcare policies should focus on rising the responsibility of communities and individuals for better treatments and services and better access to information on healthcare providers. Value The paper is an empirically based study of the healthcare resources allocation in Romania.

ENGLISH LANGUAGE AND ROMANIAN MEDIA

Monica Condruz-Bacescu

2017-03-01

Full Text Available The paper deals with the significant increase of English words and expressions in Romanian media, in the general context of English and American words’ invasion. The premise from which we start to analyze the influence of English on Romanian audiovisual space is that this influence is specific not only to Romania, but is also found in many countries worldwide. Massive borrowing of Anglo-American terms was obvious after the Second World War in most European languages. This paper constitutes an awareness call to all communication specialists, putting particular emphasis on journalists’ role and those responsible in communication to convey future generations a constant concern for all that means Romanian language. The second part of the paper presents examples of necessary borrowings and luxury Anglicisms from different fields: economic, financial, trade, education and research; sports, communication and media terminology. Then, the next part deals with examples from Romanian newspapers, magazines, from TV and radio. The media, the main providers of Anglicisms, have built a secondary reality, relying on information, reports and interpretations which they select, order them according to priorities, and spread them among the public, using a certain terminology. The attitude of speakers and specialists to the avalanche of English terms in Romanian audiovisual language must be a rational one, since it is necessary to measure both advantages and disadvantages. Therefore, in this paper I wish to plead for quality in journalistic expression without blaming the use of anglicisms or neologisms regardless of the language of origin. On the contrary, I would like to emphasize that, when their use is justified in terms of terminology and when they come to cover a semantic void or a more precise meaning, borrowings may be a demonstration of spirituality, enrichment, networking and integration of science and modern technology. The conclusion is that the

Full Text Available Drawing on ethnographic and anthropological research on the Romanian communities in Eastern Serbia, this article seeks to contribute to the global scholarship on diaspora and migration. It reveals interesting differences between the well defined and intensely studied notion of “diaspora” on the one hand, and the understudied, but useful concept of “near diaspora” on the other. First, the presence of Romanians in Eastern Serbia is looked at from a gender perspective, in the wider context of feminization of international migration. Second, the paper argues that the Romanian women in Eastern Serbia adopt the strategy of living in the “social fog”, thus becoming what can be termed “foggy diaspora”.

Full Text Available Nowadays, marketing has become a central part of libraries’ interest worldwide. Their motivation is varied: the missions of organizations have lost compatibility with market demand, budgets are low, while their units require more funds, the increase in the competition for funding, the harsh competition between service suppliers, etc. Furthermore, the Western world understood the necessity of library marketing for reasons like: the support offered in library management, the focus on consumers, the capacity of attracting consumers to use libraries, the improvement of the organization’s image. Despite all that, most Romanian libraries do not understand the part played by marketing in the library or in the information service, as well as its usefulness in day-to-day activities. The purpose of this essay is to present the importance of marketing in the National Romanian Library’s activity.

The building materials were produced through changing raw material ingredient, baking temperature, pressure difference between surface and interior of building material, grain diameter etc. Experiment indicates that change of raw material ingredient ratio can obviously influence the radon exhalation from building material, followed by baking temperature; and pressure difference does not have significant influence on radon exhalation. For the factory to produce shale-brick, the radon exhalation is relatively low under the condition that coal gangue accounts for 40%-50%, the grain diameter is less than 2 mm, the baking temperature is about 960 degree C or 1 020 degree C and the pressure difference is 85 kPa.

A survey was done on natural radioactivity level and annual effective dose rate of main building materials in Baotou, China. The natural radionuclides of 40 K, 232 Th and 226 Ra in main building materials collected from Baotou were measured using NaI γ-ray spectrometry and the measured data were analyzed according to the national standards and radiological protection principles of the European Commission. The specific activities of 40 K, 232 Th and 226 Ra in the building materials samples were 218.82-1145.92, 19.75-1.32.50 and 11.46-82.66 Bq/kg, respectively. The internal and external exposure indexes of building materials were 0.06-0.41 and 0.28-0.70, respectively. The annual effective dose equivalent was 0.41-0.97 mSv/y. This justifies the production and sale of the main building materials, as both the internal and external exposure indexes of building materials are less than 1. The effective dose rate of ash brick is 0.97 mSv/y, while the maximum acceptable value is 1 mSv/y. Therefore, it is necessary to control the amount of industrial waste residue in building materials to avoid unnecessary radioactive exposure to residents. (authors)

Vieru, Gheorghe

2006-01-01

Full text: The transport of radioactive materials (RAM) is a very important problem taking into consideration its potential risks over the environment and the radiological consequences of this activity. Romania as a Member State of the International Atomic Energy Agency has implemented national regulations for a safe transport of RAM in complying with the Agency's recommendations as well as other international specialized organizations. The paper will present the main sources of radioactive materials in Romania, and their transportation routes with a particular focus on the radioactive wastes (very low level and mixed low-level radioactive materials), radioactive isotopes and sources, and natural uranium ore. Starting from the fact that the safety in the transport of radioactive materials is dependent on packaging appropriate for the contents being shipped, rather than operational and/or administrative actions required for the package, the paper presents, very briefly, the qualification tests for the main packages used for transport and storage of RAM in Romania. There are presented also specific problems related to the identification and evaluation of the environmental risks and impacts as well as the potential radiological consequences associated with the transport of radioactive materials, for all those three possible situations: routine transport (without incidents), normal transport (with minor incidents) and during potential accidents. As a conclusion, it is stated that the evaluated annual collective dose for the population due to RAM transport is less than those received by natural radiation sources. At the same time it is concluded that Romanian made packages are safe and prevent loss of its radioactive contents into environment. (author)

2012-01-01

Five cement- and five lime-based building materials were examined in an environmental chamber for their emissions of Volatile Organic Compounds (VOCs). Typical VOCs were below detection limits, whereas not routinely analysed VOCs, like neopentyl glycol (NPG), dominated the cement-based products emissions, where, after 72 h, it was found to occur, in levels as high as 1400 μg m −3 , accounting for up to 93% of total VOCs. The concentrations of NPG were not considerably changed between the 24 and 72 h of sampling. The permeability of building materials was assessed through experiments with a dual environmental chamber; it was shown that building materials facilitate the diffusion of chemicals through their pores, reaching equilibrium relatively fast (6 h). - Highlights: ► Neopentyl glycol is reported in emissions from building materials for the first time. ► Neopentyl glycol dominates the VOC emissions from cement-based building materials. ► A dual chamber was developed to control diffusion through building materials. ► Building materials facilitate diffusion of indoor air pollutants through their pores. - Neopentyl glycol was detected in high concentrations in emissions from building materials.

This investigation deals with the following items: (a) Some building materials cause an increase of the natural radioactive radiation level indoors, especially building materials containing a certain kind of phosphogypsum. The radiation level depends among other things on the applied quantity of building materials and on the location in the building (walls, floors or roofs, etc.). The soil underneath dwellings can also be an important radiation source. The report gives a listing of the kind of building materials used for dwellings in The Netherlands, both present ones as well as possible future ones. A survey of the quantities applied and the location of application in dwellings is also given. The different types of soil underneath the dwellings are discussed. (b) Samples were collected from various factories, dealers and other sources (both present and future samples) of the most important building materials and components thereof. The samples were handed over to Division of Technology for Society TNO, Radiological Service TNO and Netherland Energy Research Foundation, in order to measure the activity concentrations and the radon exhalations. A listing of the samples is given. (Auth.)

Full Text Available As advertisements are broadcast on a daily basis, Romanian consumers are subject to an intensive media bombardment designed to influence them, trigger certain emotions, and make them develop an attitude to a particular brand or product. When designing the advertisement, great care must be taken so that it conveys positive feelings and emotions and fosters favourable attitudes to a brand. The object of the current research is to determine how consumers are able to assess the advertisement phenomenon in general and the TV commercials in particular. Based on a representative sample of 550 Romanian consumers from the urban population, the study highlights the Romanian consumers’ attitude to various types of advertisements, endorsers and creative strategies used to design and execute the advertisements. The managerial as well as the scientific implications are considered by means of the correlations made according to the respondents’ social and demographic characteristics.

Building materials and their additives contain radioactive isotopes, which can increase both external and internal radioactive exposures of humans. In this study Hungarian natural (adobe) and artificial (brick, concrete, coal slag, coal slag concrete and gas silicate) building materials were examined. We qualified 40 samples based on their radium equivalent, activity concentration, external hazard and internal hazard indices and the determined threshold values of these parameters. Absorbed dose rate and annual effective dose for inhabitants living in buildings made of these building materials were also evaluated. The calculations are based on (226)Ra, (232)Th and (40)K activity concentrations determined by gamma-ray spectrometry. Measured radionuclide concentrations and hence, calculated indices and doses of artificial building materials show a rather disparate distribution compared to adobes. The studied coal slag samples among the artificial building materials have elevated (226)Ra content. Natural, i.e. adobe and also brick samples contain higher amount of (40)K compared to other artificial building materials. Correlation coefficients among radionuclide concentrations are consistent with the values in the literature and connected to the natural geochemical behavior of U, Th and K elements. Seven samples (coal slag and coal slag concrete) exceed any of the threshold values of the calculated hazard indices, however only three of them are considered to be risky to use according to the fact that the building material was used in bulk amount or in restricted usage. It is shown, that using different indices can lead to different conclusions; hence we recommend considering more of the indices at the same time when building materials are studied. Additionally, adding two times their statistical uncertainties to their values before comparing to thresholds should be considered for providing a more conservative qualification. We have defined radon hazard portion to point

The radionuclide contents of typical building materials used in Hong Kong were studied by γ spectroscopic analysis. The physical properties of these building materials affecting the production and transportation of 222 Rn to the surrounding air were examined; these include the emanation coefficient of 2 '2 2 Rn of the material, the diffusion coefficient of 222 Rn in the material and the effect of surface coating and temperature on the rate of 222 Rn exhalation. Results obtained in this study explain the indoor 222 Rn concentration observed in our previous surveys and also suggest that the main source of indoor 222 Rn in Hong Kong is building material.

Building materials contain natural radionuclides (226)Ra, (232)Th and (40)K, which cause direct radiation exposure of the public. The concentrations of (226)Ra, (232)Th and (40)K in commonly used building materials of Urumqi, China have been analysed using gamma-ray spectrometry. The concentrations of (226)Ra, (40)K and (232)Th in the studied building materials range from 19.8 to 87.4, from 273.3 to 981.2 and from 11.6 to 47.7 Bq kg(-1), respectively. The radium equivalent activity (Raeq), gamma index (Iγ) and alpha index (Iα) were calculated to assess the radiation hazards to people living in dwellings made of the materials studied. The calculated Raeq values of all the building materials are lower than the limit of 370 Bq kg(-1) for building materials. The values of Iγ and Iα of all the building materials are less than unity. The study shows that these materials may be safely used as construction materials and do not pose significant radiation hazards.

The Euratom BSS requires that in the near future (2015) the building materials for application in dwellings or buildings such as offices or workshops are screened for NORM nuclides. The screening tool is the activity concentration index (ACI). Therefore it is expected that a large number of building materials will be screened for NORM and thus require ACI determination. Nowadays, the proposed standard for determination of building material ACI is a laboratory analyses technique with high purity germanium spectrometry and 21 days equilibrium delay. In this paper, the B-NORM method for determination of building material ACI is assessed as a faster method that can be performed on-site, alternative to the aforementioned standard method. The B-NORM method utilizes a LaBr 3 (Ce) scintillation probe to obtain the spectral data. Commercially available software was applied to comprehensively take into account the factors determining the counting efficiency. The ACI was determined by interpreting the gamma spectrum from 226 Ra and its progeny; 232 Th progeny and 40 K. In order to assess the accuracy of the B-NORM method, a large selection of samples was analyzed by a certified laboratory and the results were compared with the B-NORM results. The results obtained with the B-NORM method were in good correlation with the results obtained by the certified laboratory, indicating that the B-NORM method is an appropriate screening method to assess building material ACI. The B-NORM method was applied to analyze more than 120 building materials on the Belgian market. No building materials that exceed the proposed reference level of 1 mSv/year were encountered. -- Highlights: • Many building materials will have to be tested for NORM activity concentrations. • An on-site NORM analysis method has been developed and validated. • Over 120 building materials on the Belgian market have been analyzed with this method. • The Euratom BSS reference level of 1 mSv/year excess dose will

Effects of energy and carbon taxes on building material competitiveness

2007-04-15

The relations between building material competitiveness and economic instruments for mitigating climate change are explored in this bottom-up study. The effects of carbon and energy taxes on building material manufacturing cost and total building construction cost are modelled, analysing individual materials as well as comparing a wood-framed building to a reinforced concrete-framed building. The energy balances of producing construction materials made of wood, concrete, steel, and gypsum are described and quantified. For wood lumber, more usable energy is available as biomass residues than is consumed in the processing steps. The quantities of biofuels made available during the production of wood materials are calculated, and the cost differences between using these biofuels and using fossil fuels are shown under various tax regimes. The results indicate that higher energy and carbon taxation rates increase the economic competitiveness of wood construction materials. This is due to both the lower energy cost for material manufacture, and the increased economic value of biomass by-products used to replace fossil fuel. (Author)

The aim of the work was to analyse the effective 226 Ra content of building- and back filling materials used in Hungary. The quantity of radon was determined by ionization chambers connected to vibrating-reed electrometers, as well as by a scintillation radon counter. The radon measuring instruments were calibrated by known 222 Rn quantities given off from standard RaCl 2 solutions. The overall uncertainty of the data obtained is estimated as being 25%. The minimum measurable effective 226 Ra concentration due to a 10 4 g building material source is calculated as 16 fCi/g for the ionization chambers and 8 fCi/g for the scintillation counter. 68 building material samples and 11 backfill (concrete made by fly-ashes) samples have been studied and it has been found, that the effective 226 Ra contents of the tested building materials are 2 to 9 times greater than those found in the Soviet Union though none exceeds the recommended 600 fCi/g level. Among the back filling materials made with fly-ash the maximum 226 Ra content was 3300 fCi/g. The effective 226 Ra content measurements are well suited for a priori radon escape qualification of building materials. (K.A.)

The concept of ‘Trinity’ in Dante’s Paradise as reflected in Romanian translations

Directory of Open Access Journals (Sweden)

Cristian Ungureanu

2015-07-01

Full Text Available The translator of Dante’s Paradise is faced with a double difficulty. The first results from the limitation—inherent in the human condition—to express the ineffable, which the author experiences; the second stems from the difficulty of language that Dante himself builds in order to overcome the first difficulty. The success or the failure of a translation is measured in terms of how much of the original message the translator manages to make available to the reader in a foreign language, and this percentage can only be revealed by comparative analysis. Therefore, this paper starts from a comparative analysis between the original text of the Paradise and its Romanian translations, with a focus on the contexts that foster the concept of ‘Trinity’; the analysis carried out on the Romanian versions revealed both successful equivalences, semantically and formally faithful to the original, and cases of “betrayal” of the original text.

Full Text Available There are several terms used in Romanian for the English term supply chain. We have counted eleven. It has been adopted in several ways and it is perceived (adapted in several ways in Romania. There are several causes which have determined this fact: the English terminology inconsistence regarding supply chain has been translated into other languages, professionals roots determine the usage (logistics professionals use it for logistics, strategic logistics use it in general etc., the lack of Romanian discussions regarding the new professional terminology at general level and supply chain and logistics in particular. We expose the different ways by which supply chain is reflected in Romanian, we discuss the causes which have generated this total confusion and then we suggest a proper term for supply chain in Romanian, considering the real meaning of the term and the strategies adopted by other countries regarding supply chain adoption. In conclusion, we propose a general adoption and adaptation for the term in Romanian.

Full Text Available The purpose of this paper is to present preliminary specific issues concerning the vision and the strategic thinking of the managers of Romanian fast growing firms in the years of rapid growth. This paper clarifies two research questions. (1 The first research question is what is the message of the manager's vision of the Romanian fast growing firms? Therefore, we must first verify if the managers of the Romanian fast growing firms have a concrete vision about the business they run and if so, what is the vision of the managers about the companies that they lead? (2 The second research question is what findings can be drawn about the role of strategic thinking of the managers in the management of the Romanian fast growing firms? The research that we have conducted is a qualitative research. The research method that we used is the interview. The interview is specific to qualitative research. Regarding the method of analysis that we used it is the content analysis. The research was conducted on a total of 17 Romanian fast growing firms that are located in Timiș County. The firms were identified based on a specific selection criteria set after a thorough review of the literature in the field. The 17 companies that we have analysed represent the foundation of 17 in-depth case studies, which we believe helped us to better understand what it means in the Romanian context to grow fast, through the entrepreneurs managers vision and strategic thinking. The results presented in this paper come to strengthen the results reached by other researchers in this field. The results present an image of the current Romanian context – about the role of strategic thinking of the entrepreneur manager in the management of Romanian fast growing firms. The paper presents a detailed analysis of managers' vision of the Romanian fast growing firms. The paper also presents findings about the role of strategic thinking in helping managers achieve rapid growth in the

The transition to secure, sustainable, low-energy systems will have a significant effect on the way in which we design and construct new buildings. In turn, the new buildings that are constructed will play a critical role in delivering the better performance that would be expected from such a transition. Buildings account for about half of UK carbon dioxide (CO 2 ) production. So it is urgent to ensure that energy is used efficiently in existing buildings and that new building stock is better able to cope with whatever the future holds. Most energy used in buildings goes towards heating, lighting and cooling, but a growing percentage is consumed by domestic appliances, computers and other electrical equipment. Actual energy consumption is the product of a number of factors, including individual behaviours and expectations, the energy efficiency of appliances and the building envelope. This review focuses on the third of these, the building itself, and its design and construction. It discusses the issues faced by the construction industry today, suggesting that major changes are needed relating to materials, techniques, skills and innovation. It moves on to consider future advances to 2050 and beyond, including developments in ICT, novel materials, skills and automation, servitisation (the trend for manufacturers to offer lifetime services rather than simple products), performance measurement and reporting, and resilience. We present a vision of the new build construction industry in 2050 and recommendations for policy makers, industry organisations and construction companies

2012-12-01

Full Text Available The rural inhabitants need to face and survive structural changes in rural economy and, thus, to become more market oriented. Traditions and old skills were somehow lost and new activities were approached. In order to reach them, public policy intervened and supported several types of activities. The public authorities demand Romanian inhabitants from rural areas to be truly competitive in a fully shacked economy. Therefore, the research question is: what are the premises and challenges that Romanian inhabitants from rural areas confront to? Entrepreneurial skills of Romanians in rural areas are a matter of national interest. The problem of entrepreneurships has, at least, two meanings in the present paper: the premises and challenges of the free manifestation of private initiative and the importance of this manifestation for national economy. The approach is pragmatic, for public policy. The main objectives of the research are: to identify the premises and challenges of the entrepreneurship in Romanian rural areas and to elaborate relevant solution for public policy in order to conduct to robust rural economy as a result of entrepreneurial expression. Therefore, next financial plan of the Romanian national Rural Development Programme 2014-2020 needs to take into consideration the premises and challenges of entrepreneurship, as this is the only pertinent solution for added value creation in rural economy. And the strategic approach is to define the future profile of Romanian rural inhabitant.

Full Text Available The object of this qualitative sociology study was to emphasize the identity attributes of Romanians today: what they think of themselves as a people and what Romanians who live in the country or in other countries in the world think about Romania. The theoretical framework was established by social identity theory and by social representations research. For the gathering of data, I used a questionnaire with open questions and the reflection-and answer-triggering method, using as stimulus patriotic-themed songs: lyrics from the national anthem and another patriotic song very well known in Romania, entitled "God, protect the Romanians!". For the analysis of qualitative data, I used a category scheme specific for social representations, and at the end of the article I synthesized the data in the form of "storytelling" representative for four social categories included in the research: students, managers, pensioners and Romanian migrants abroad. The data obtained point to an identity crisis among these categories of Romanians: this crisis takes the form of a negative national identity. In terms of the social identity theory (Tajfel, it means that Romanians have in general a negative image when comparing themselves with other nations and they feel it like a strong discomfort.

Rehabilitation of adobe buildings. Understanding different materials from Portugal

Earth construction is the oldest building material known, with documented cases of the use of earth bricks since Mesopotamia around 10 000 BC (Heathcote, 1995). The earth construction exists throughout the majority of the world in different cultures, and for some countries, nowadays it continues to be the main process of construction (Vega et al, 2011). Around 30% of the world's population lives in buildings made of earth materials. Earthen construction is an environmentally friendly technique with a social and cultural contribution; this advantage is increased when this type of construction is applied in developing countries where the material costs counterbalance with labour costs, and where other materials and techniques cannot be available (Ciancio et al, 2013). Studies of materials characterization are required in order to understand the composition and specific properties of the earth buildings, their heterogeneity and their degradation mechanisms. Some adobes from different buildings, ages and regions of Portugal were collected in order to characterize them (mineralogically, chemically and physically). It was possible to understand the composition of these materials and their differences. Main minerals are quartz, feldspars, calcite and phyllosilicates (mica and kaolinite). The mechanical behaviour of these materials isn't the best, but it is possible to improve it with some simple and cheap natural additives (kaolinitic soils). The characterization of these materials allows us to understand the differences between the materials from the different regions (controlled by locally available raw materials). Understanding these materials, and their properties, it is possible to formulate new ones for repair, conservation and rehabilitation works. The adobe bricks are an alternative of kiln baked bricks which has several advantages and one of the most important is that these materials are recyclable. Adobes are an excellent option for building rehabilitation, if

The impact of roofing material on building energy performance

Science.gov (United States)

Badiee, Ali

The last decade has seen an increase in the efficient use of energy sources such as water, electricity, and natural gas as well as a variety of roofing materials, in the heating and cooling of both residential and commercial infrastructure. Oil costs, coal and natural gas prices remain high and unstable. All of these instabilities and increased costs have resulted in higher heating and cooling costs, and engineers are making an effort to keep them under control by using energy efficient building materials. The building envelope (that which separates the indoor and outdoor environments of a building) plays a significant role in the rate of building energy consumption. An appropriate architectural design of a building envelope can considerably lower the energy consumption during hot summers and cold winters, resulting in reduced HVAC loads. Several building components (walls, roofs, fenestration, foundations, thermal insulation, external shading devices, thermal mass, etc.) make up this essential part of a building. However, thermal insulation of a building's rooftop is the most essential part of a building envelope in that it reduces the incoming "heat flux" (defined as the amount of heat transferred per unit area per unit time from or to a surface) (Sadineni et al., 2011). Moreover, more than 60% of heat transfer occurs through the roof regardless of weather, since a roof is often the building surface that receives the largest amount of solar radiation per square annually (Suman, and Srivastava, 2009). Hence, an argument can be made that the emphasis on building energy efficiency has influenced roofing manufacturing more than any other building envelope component. This research project will address roofing energy performance as the source of nearly 60% of the building heat transfer (Suman, and Srivastava, 2009). We will also rank different roofing materials in terms of their energy performance. Other parts of the building envelope such as walls, foundation

Build Green is a certification program that will identify and label building products with a known recycled content. The introduction of these recycled materials has raised the concern that they may emit more indoor pollutants than conventional materials. This study addresses that concern by analyzing Build Green and conventional materials to assess their potential for off-gassing. The study involved emission tests of 37 materials including carpets, carpet undercushions, structural lumber, foundation material, insulation, drywall, fiberboard, counter tops, and cabinetry. The results presented in this report include comparisons of Build Green and conventional materials in terms of emissions of volatile organic compounds and formaldehyde, the material loading ratio, and discussion of the specific sources of the emissions.

A SIMPLE ASSESSMENT OF FISCAL SUSTAINABILITY FOR THE ROMANIAN ECONOMY

Directory of Open Access Journals (Sweden)

ALEXANDRU LEONTE

2011-04-01

Full Text Available The financial crisis has seriously impacted the economies around the world, emerging and developed alike. With interest rates at historical low levels, constrained in many cases by the zero lower bound, the emphasis is put on fiscal policy to restore the economies on the path of sustainable growth. This paper attempts to shed light on the issue of fiscal sustainability of the Romanian economy, by checking if the intertemporal fiscal constraint of the government is respected. According to the constraint, the current value of debt equals the sum of the discounted values of future government surpluses, which means that the government is not financing itself through a Ponzi scheme. I build on the econometric approach used in papers such as Hamilton and Flavin (1986, Hakkio and Rush (1991, Quintos (1995, Santos Bravo and Silvestre (2002, Bohn (2007. More specifically, I focus on the time series properties of government debt, revenue and expenditure, determining: i the order of integration for the government debt series; ii whether or not government revenue and expenditure are cointegrated. Thus I am able to evaluate the strength of the fiscal position of the Romanian economy and to see the impact of the financial crisis on this position.

Full Text Available In Romania local autonomy is administrative and financial. If local financial resources are not independent from the state budget and they continue to depend on it exclusively and if financial independence remains only a target which has not been materialized in practice, then the administrative autonomy of the communes, towns and counties will not yield the expected results and will still be limited. According to the European Charter of Local Self-Government the financial resources available for the Local Government authorities should be correlated, commensurate with their duties and their decentralized competences. A recent decision of the Romanian Constitutional Court sustains the same idea. Having in mind this CC’s Decision, the provisions of the European Charter of Local Self-Government and the nowadays insolvent Romanian administrative-territorial units, allow me to underline in this paper my opinion that the financial autonomy is the substance of local autonomy.

China hosts a large amount of building stocks, which is nearly 50 billion square meters. Moreover, annual new construction is growing fast, representing half of the world's total. The trend is expected to continue through the year 2050. Impressive demand for new residential and commercial construction, relative shorter average building lifetime, and higher material intensities have driven massive domestic production of energy intensive building materials such as cement and steel. This paper developed a bottom-up building stock turnover model to project the growths, retrofits and retirements of China's residential and commercial building floor space from 2010 to 2050. It also applied typical material intensities and energy intensities to estimate building materials demand and energy consumed to produce these building materials. By conducting scenario analyses of building lifetime, it identified significant potentials of building materials and energy demand conservation. This study underscored the importance of addressing building material efficiency, improving building lifetime and quality, and promoting compact urban development to reduce energy and environment consequences in China. - Highlights: •Growths of China's building floorspace were projected from 2010 to 2050. •A building stock turnover model was built to reflect annual building stock dynamics. •Building related materials and energy demand were projected.

Most building materials of natural origin contain small amounts of Naturally Occurring Radioactive Materials (NORMs), mainly radionuclides from the 226 Ra and 232 Th decay chains and 40 K. The origin of these materials is the earths crust, but they find their way into building materials, air, water, food and the human body itself. The worldwide average indoor effective dose due to gamma rays from building materials is estimated to be about 0.4 mSv per year. In many parts of the world, building materials containing radioactive materials have been used for generations. As individuals spend more than 80% of their time indoors, the internal and external radiation exposure from building materials creates prolonged exposure situations. The internal (inhalation) radiation exposure is due to 222 Rn and their short lived decay products exhaled from building materials into the room air. The average activity concentrations of 226 Ra, 232 Th and 40 K in the earths crust are 35, 30 and 400 Bq/kg respectively. However, elevated levels of natural radionuclides causing annual doses of several mSv were identified in some regions around the world. Recycled industrial by-products containing Technologically Phosphogypsum, a by-product in the production of phosphate fertilizers is used as building material, and red mud, a waste from primary aluminum production, is used in bricks, ceramics and tiles. The increased tendency of the building material industry to use industrial wastes as substitutes for natural products having relatively high activity concentration of NORMs and the increased exposure caused by them were the driving forces for undertaking the present investigation.

The Option 9, Cool Communities, of the Clinton-Gore Climate Change Action Plan (CCAP) calls for mobilizing community and corporate resources to strategically plant trees and lighten the surfaces of buildings and roads in order to reduce cooling energy use of the buildings. It is estimated that Cool Communities Project will potentially save over 100 billion kilowatt-hour of energy per year corresponding to 27 million tons of carbon per year by the year 2015. To pursue the CCAP`s objectives, Lawrence Berkeley Laboratory (LBL) on behalf of the Department of Energy and the Environmental Protection Agency, in cooperation with the Building and Fire Research Laboratory of the National Institute of Standards and Technology (NIST), organized a one-day meeting to (1) explore the need for developing a national plan to assess the technical feasibility and commercial potential of high-albedo (``cool``) building materials, and if appropriate, to (2) outline a course of action for developing the plan. The meeting took place on February 28, 1994, in Gaithersburg, Maryland. The proceedings of the conference, Cool Building Materials, includes the minutes of the conference and copies of presentation materials distributed by the conference participants.

Although an explosion of new building materials are being introduced into today's market, adequate up-front research into their chemical and physical properties as well as their potential health and environmental consequences is lacking. History has provided us with several examples where building materials were broadly deployed into society only to find that health and environmental problems resulted in unintended sustainability consequences. In the following paper, we use lead and asbestos as legacy building materials to show their similar historical trends and sustainability consequences. Our research findings show unintended consequences such as: increased remediation and litigation costs; adverse health effects; offshoring of related industries; and impediments to urban revitalization. As numerous new building materials enter today's market, another building material may have already been deployed, representing the next "asbestos." This paper also proposes an alternative methodology that can be applied in a cost-effective way into existing and upcoming building materials, to minimize and prevent potential unintended consequences and create a pathway for sustainable communities. For instance, our findings show that this proposed methodology could have prevented the unintended incurred sustainability costs of approximately $272-$359 billion by investing roughly $24 million in constant 2014 U.S. dollars on up-front research into lead and asbestos.

Full Text Available Fair value generated intense debate during the last years, as the financial turmoil influenced many economies and capital markets, including the Romanian ones, too. Some researchers and professionals consider fair value in charge with the financial crisis and they ask for historical cost accounting basis for financial reporting. Fair value has its supporters, too. They consider that fair value reflects the effects of changes in market conditions when they take place, and accounting information is more reliable in this framework. Following recent regulations, Romanian entities activating on capital market as investors in capital market instruments, or whose shares are traded on a regulated market, must prepare their individual financial statements in accordance with the International Financial Reporting Standards. The study provides some conclusions that could enlarge the utility of fair value related to entities that activate on Romanian capital market.

Full Text Available The substantial improving of the energy efficiency is essential to meet the ambitious energy goals of the EU. About 40% of the European energy consumption belongs to the building sector. Therefore the reduction of the energy demand of the existing building stock is one of the key measures to deliver a substantial contribution to reduce CO2-emissions of our society. Buildings of the future have to be efficient in respect to energy consumption for construction and operation. Current research activities are focused on the development of functional materials with outstanding thermal and optical properties to provide, for example, slim thermally superinsulated facades, highly integrated heat storage systems or adaptive building components. In this context it is important to consider buildings as entities which fulfill energy and comfort claims as well as aesthetic aspects of a sustainable architecture.

The isotope 222Rn is responsible for approximately half of the effective annual dose received by the world population. The decay products of 222Rn interacting with the cells of biological tissue of lungs have very high probability to induce cancer. The present survey was focused in the evaluation of activity concentration of 222Rn and other radioisotopes related to the building materials at workplaces at Curitiba - Paraná State. For this purpose, the instant radon detector AlphaGUARD (Saphymo GmbH) was used to measure the average concentrations of 222Rn in building materials, which were also submitted to gamma spectrometry analysis for qualitative and quantitative evaluation of the radionuclides present in samples of sand, mortar, blue crushed stone (Gneissic rock), red crushed stone (Granite), concrete and red bricks. The main radionuclides evaluated by gamma spectrometry in building material samples were 238U/226Ra, 232Th and 40K. These measurements were performed at the Laboratory of Applied Nuclear Physics of the Federal University of Technology - Paraná in collaboration with the Center of Nuclear Technology Development (CDTN - CNEN). The results of the survey present the concentration values of 222Rn related to construction materials in a range from 427±40.52 Bq/m³ to 2053±90.06 Bq/m³. The results of gamma spectroscopy analysis show that specific activity values for the mentioned isotopes are similar to the results indicated by the literature. Nevertheless, the present survey is showing the need of further studies and indicates that building materials can contribute significantly to indoor concentration of 222Rn.

Romania is one of the most active seismic countries in Europe, with more than 500 earthquakes occurring every year. The seismic hazard of Romania is relatively high and thus understanding the earthquake phenomena and their effects at the earth surface represents an important step toward the education of population in earthquake affected regions of the country and aims to raise the awareness about the earthquake risk and possible mitigation actions. In this direction, the first national educational project in the field of seismology has recently started in Romania: the ROmanian EDUcational SEISmic NETwork (ROEDUSEIS-NET) project. It involves four partners: the National Institute for Earth Physics as coordinator, the National Institute for Research and Development in Construction, Urban Planning and Sustainable Spatial Development " URBAN - INCERC" Bucharest, the Babeş-Bolyai University (Faculty of Environmental Sciences and Engineering) and the software firm "BETA Software". The project has many educational, scientific and social goals. The main educational objectives are: training students and teachers in the analysis and interpretation of seismological data, preparing of several comprehensive educational materials, designing and testing didactic activities using informatics and web-oriented tools. The scientific objective is to introduce into schools the use of advanced instruments and experimental methods that are usually restricted to research laboratories, with the main product being the creation of an earthquake waveform archive. Thus a large amount of such data will be used by students and teachers for educational purposes. For the social objectives, the project represents an effective instrument for informing and creating an awareness of the seismic risk, for experimentation into the efficacy of scientific communication, and for an increase in the direct involvement of schools and the general public.

Common building materials collected from Xianyang, China were analyzed for the natural radioactivity of 226 Ra, 232 Th and 40 K using γ-ray spectroscopy. The average activity concentration of 226 Ra, 232 Th and 40 K in the studied building materials ranges from 13.4 to 69.9, 13.1–99.1 and 124.7–915.1 Bq kg −1 , respectively. The measured activity concentrations for these radionuclides were compared with the reported data of other countries and with the worldwide average activity of soil. To assess the radiation hazard of the natural radioactivity in all samples to the people, the radium equivalent activity, external hazard index, internal hazard index, indoor absorbed dose rate and total annual effective dose were estimated. The radium equivalent activities of the studied samples are below the internationally accepted values. The external hazard index and internal hazard index of all analyzed building materials are less than unity. The mean values of indoor absorbed dose rate for all building materials except for lime are higher than the world population-weighted average of 84 nGy h −1 and the total annual effective dose values of building materials are lower than 1 mSv y −1 except for some cyan brick samples. The study shows the measured building materials do not pose significant source of radiation hazard and are safe for use in the construction of dwellings. - Highlights: ► Natural radioactivity in building materials was determined by gamma ray spectrometry. ► The radiological hazard of studied building materials is within the recommended safety limit. ► Most of the studied building materials do not pose significant radiation risk to residents.

Full Text Available The performance of public administration is one of the top priorities of the national governments worldwide, not only for Romania. The role of a performing management system at the level of public administration is to ensure a high quality and efficiency of the adopted policies and strategies, of the provided public services and of the administrative act itself, and to guarantee the advantage of a competitive and efficient administration both in relation to its own citizens, and in competition with other cities and countries throughout Europe and all around the world. Following these considerations, and based upon an empirical research conducted with the aid of a survey regarding ‘The analysis of the performance level of the Romanian public administration’ the article aims to (1 identify modern management tools that determine and influence the performance of Romanian public institutions, (2 analyze the effects of using project management as organizational capacity development instruments by public administration in Romania, and (3 determine the influence and effects of the external factors on the performance and development of Romanian public administration.

Romanian-Bulgarian Religious Relations during the First World War

Full Text Available After the outbreak of the First World War, when Bulgaria joined the Central Powers through the alliance with Germany, and Romania joined the Entente, the religious relations had a few special times. The defeat of the Romanian army in Dobrudgea and its occupation by the German – Bulgarian troops brought about a real exodus of the Romanian Orthodox clergy who took refuge especially to Moldova. The war ruined a few churches of Dobrudgea and destroyed the houses of the priests who had left their parishes. The issue of the priests fled from Dobrudgea was discussed within a Council met in Iasi in the summer of 1918, when the participants tried to find solutions for their return to their parishes. I personally examined the documents of this council found today in the Archives of the Metropolitanate of Moldova and Bucovina, because they reveal the deficiencies of the Romanian Orthodox Church in regard to the administrative organisation both in Dobrudgea and in the Quadrilateral. Our study approaches two major events occurred in the Bucharest occupied by the German-Bulgarian troops: the Te-Deum service celebrated in the honour of the royal family of Bulgaria in the Metropolitan Cathedral and the attempt to steal the Holy Relics of Pious Dimitrios Basarabov. The German administration has also been involved in the two events, because the Primate metropolitan Conon asked them to resolve these religious Romanian- Bulgarian conflicts. The documents which mention the two events can be found in the Archives of the Holy Synod of Bucharest and have a special significance because they represent an aspect less examined of the First World War and of the Romanian-Bulgarian relations. The theme of this study has never been approached so far by the Romanian theologians and historians, the research covering a gap in the study of the history of the First World War and of the Romanian- Bulgarian relations.

The Romanian Institute for Nuclear Research (INR) has a set of nuclear facilities consisting of TRIGA 14 MW(th) materials testing reactor and LEPI (Romanian acronym for post-irradiation examination laboratory) which enable to investigate the behaviour of the nuclear fuel and materials under various irradiation conditions. The available techniques of post-irradiation examination (PIE) and purposes of PIE for CANDU reactor fuel are as follows. 1) Visual inspection and photography by periscope: To examine the surface condition such as deposits, corrosion etc. 2) Eddy current testing: To verify the cladding integrity. 3) Profilometry and length measurement performed both before and after irradiation: To measure the parameters which highlight the dimensional changes i.e. diameter, length, diametral and axial sheath deformation, circumferential sheath ridging height, bow and ovality. 4) Gamma scanning and Tomography: To determine the burnup, axial and radial fission products activity distribution and to check for flux peaking and loading homogeneity. 5) Puncture test: To measure the pressure, volume and composition of fission gas and the inner free volume. 6) Optical microscopy: To highlight the structural changes and hydriding, to examine the condition of the fuel-sheath interface and to measure the oxide thickness and Vickers microhardness. 7) Mass spectrometry: To measure the burnup. 8) Tensile testing: To check the mechanical properties. So far, non-destructive and destructive post-irradiation examinations have been performed on a significant number of CANDU fuel rods (about 100) manufactured by INR and irradiated to different power histories in the INR 14 MW(th) TRIGA reactor. These examinations have been performed as part of the Romanian research programme for the manufacturing, development and safety of the CANDU fuel. The paper describes the PIE techniques and some results. (Author)

Simionescu Mihaela

2016-12-01

Full Text Available Considering the fact that Romanian economy competitiveness is not based on innovation and investment in human capital, this study makes an empirical evaluation of the impact of occupation and unemployment in Romanian counties on the economic growth. The approach based on panel vector-autoregressive (panel VAR models indicated a negative impact of occupation and activity rate in 42 Romanian counties on the economic growth during 2006-2014. On the other hand, the real economic growth was achieved at high unemployment rates. These results are contrary to previous studies in literature and are due to a structural economic crisis and to lack of labour productivity and investment in human capital. Further policy measures should focus on structural unemployment decrease, more skilled labour force according to labour market needs, lifelong learning, higher performance and quality of education system, promotion of social inclusion, poverty control.

This work presents a comprehensive study of natural radioactivity in building materials used in Iran. For this purpose, 177 samples of five types of building material, i.e. cement, gypsum, cement blocks, gravel and brick, were gathered from different regions of the country and analyzed by gamma spectroscopy to quantify radioactivity concentrations using a high purity germanium (HPGe) detector and a spectroscopy system. According to the results of this investigation, cement samples had maximum values of the mean Ra-226 and Th-232 concentrations, 39.6 and 28.9 Bq/kg, respectively, while the lowest value for mean concentration of these two radionuclides were found in gypsum samples 8.1 and 2.2 Bq/kg, respectively. The highest (851.4 Bq/kg) and lowest (116.2 Bq/kg) value of K-40 mean concentration were found in brick and gypsum samples, respectively. The absorbed dose rate and the annual effective dose were also calculated from the radioactivity content of the radionuclides. The results show that the maximum values of dose rate and annual effective dose equivalent were 53.72 nGy/h and 0.37 mSv/y in brick samples. The radium equivalent activities R eq calculated were below the permissible level of 370 Bq/kg for all building materials. The values of hazard indexes were below the recommended levels, therefore, it is concluded that the buildings constructed from such materials are safe for the inhabitants. The results of this study are consistent with the results of other investigations in different parts of the world. (authors)

Radon is a radioactive inert gas, which is produced during the decay of radium, an element present in the naturally occurring uranium series. In the recent past, environmental scientists all over the world have been expressing great concern about the radiation hazard from radon and its short lived daughter products inside buildings. The radon concentration inside a building depends upon the radon exhalation from the building materials used for the construction and the soil underneath the building. In the present investigations, a comparative study for radon exhalation rate has been carried out in some Indian and Pakistani cements and other building materials being used locally such as sand, soil, bricks, marbles, CaCO 3 , POPs by using Track Etch Technique. The Pakistani cement with the trade name 'Elephant' shows the minimum mass exhalation rate while the Indian 'Birla White' cement has shown the maximum. Among the other building materials studied, CaCO 3 has shown the minimum, while local soil the maximum mass exhalation rate. Out of the fired clay bricks, roof tiles, floor tiles and different marbles, floor tiles have the minimum areal exhalation rate while roof tiles the maximum. (author)

2011-01-01

Full Text Available In this paper, I have done a research on the positioning of Romanian wines. The positioning is a necessary approach of brands to have a privileged position in the minds of consumers. In front of the keen foreign competition, the Romanian wine brands must assert a new identity to match the Romanian client's current lifestyle. The main objective of the research is the identification of the Romanian wine brand positioning. To achieve the objective of the research I have conducted a market research. The study was conducted on a sample of 100 respondents, consumers of Romanian wines. In the study, I have focused on a number of elements necessary for obtaining the positioning maps. Thus I tested the assisted and unassisted recognition of vineyards, the vineyards positioning depending on internal and international recognition and tradition / reputation, the vineyards positioning depending on the internal and international recognition and price, the vineyards positioning depending on sweet, red and light wines and on strong and dry wines. The positioning strategy will determine, on the one hand, the efficiency of the marketing activity at the level of consumer segment by obtaining a better image due to the high satisfaction of the specific needs, and on the other hand, the differentiation will enable to the company to gain competitive advantages, hence substantially increased profits. The theoretical contribution of this paper is to clarify the issues of positioning and to emphasize its importance. The practical contribution refers to the positioning of wines brands, which can be a model of reflection for each of the analyzed vineyards.

Creative Pluralism in Indian and Romanian Accounts of Transnational Migration

Directory of Open Access Journals (Sweden)

Stoican Adriana Elena

2016-12-01

Full Text Available The paper offers a comparative perspective on transmigrant cultural identities as illustrated in the works of two contemporary South Asian American and Romanian American authors, Jhumpa Lahiri and Aura Imbăruș. The comparison involves Gogol, a South Asian American character, and Aura, the author of the memoir Out of the Transylvania Night. Although Gogol is a fictional character and Aura is an actual transmigrant, their comparative assessment relies on the assumption that both narratives are inspired by the authors’ background of relocation. Despite their different cultural origins, both authors share thematic aspects related to the dynamics of cultural identity in the context of migration. This paper aims to provide a starting point for an enlarged framework of comparative analysis, in order to foreground intersections between different experiences of cultural negotiation in the context of displacement. Born and raised in America, Gogol is challenged by his cultural multiplicity and strives to suppress elements of his Indian identity. After years of rebelling against his parents’ norms, Gogol shifts to the Bengali model, when his father dies. Once he accepts the relevance of his cultural roots, Gogol is able to plunge into a dimension situated beyond his Bengali and American selves. His transcendent strategy is illustrated by his decision to plunge into a third space of redefinition, suggested by the Russian literature which is appreciated by Gogol’s father. Aura Imbăruș offers the example of a first generation Romanian transmigrant who undergoes voluntary relocation to the United States. Fascinated by the American world, Aura is eager to take over norms of material success and consumerism, overlooking the relevance of her cultural roots. When she undergoes a personal family crisis, Aura eventually reassesses the value of her Romanian background, aiming to reconcile her source culture with her Americanised self.

2007-07-01

The main objective of the ongoing research project described in this paper was to study the potential for reducing energy used for ventilating buildings by using low-polluting building materials, without compromising the indoor air quality. To quantify this potential, the exposure-response relationships, i.e. the relationships between ventilation rate and perceived indoor air quality, were established for rooms furnished with different categories of polluting materials and the simulations of energy used for ventilation were carried out. The exposure-response relationships were based on a summary of data reported in the literature on exposure-response relationships for materials tested in laboratory settings in small-scale glass chambers, and in full-scale in climate chambers, test rooms or normal offices. New experiments were also considered in which the effect of using low-polluting materials on perceived air quality was examined in test rooms ventilated with different outdoor air supply rates, low-polluting materials being selected in small glass chambers. The results suggest that the exposure-response relationships vary between different building materials and that the perceived air quality can be improved considerably when polluting building materials are substituted with materials that pollute less. The preliminary energy simulations indicate that selecting low-polluting materials will result in considerable energy savings as a result of reducing the ventilation rates required to achieve acceptable indoor air quality.

The Europeanization of the Romanian Society and the Tendential Modernity

Directory of Open Access Journals (Sweden)

Constantin Schifirneț

2011-01-01

Full Text Available The study examines the tendential modernity as an explanatory factor of the particularities of the Europeanization of the Romanian society. I start from the thesis that the evolution of the Europeanization process in Romania is closely associated with the process of accession to the European Union, finalized after the passing through a sinuous and difficult route. The analysis of the Europeanization of the Romanian society pursues the stages of its formation in the local context. Due to the fact thatRomaniawill still continue to be a society in transition, the most critical and relevant problem regards the dependency of the Romanian society on the strong societies inEurope. Under these circumstances, the question is, whetherRomaniawill represent a periphery ofEurope, or a national community with a European standard of development. Europeanization in its real sense does not mean “westernization”. Through the adherence to the European Union, Romanian society has the chance to put an end to the successive transitions known over its modern history, generators of tendential modernity. The Europeanization constitutes the fundamental purpose of the modernization processes of the Romanian society.

2014-10-01

The release of the organochlorine pesticide lindane (γ-hexachlorocyclohexane) from several types of contaminated building materials was studied to assess inhalation hazard and decontamination requirements in response to accidental and/or intentional spills. The materials included glass, polypropylene carpet, latex-painted drywall, ceramic tiles, vinyl floor tiles, and gypsum ceiling tiles. For each surface concentration, an equilibrium concentration was determined in the vapour phase of the surrounding air. Vapor concentrations depended upon initial surface concentration, temperature, and type of building material. A time-weighted average (TWA) concentration in the air was used to quantify the health risk associated with the inhalation of lindane vapors. Transformation products of lindane, namely α-hexachlorocyclohexane and pentachlorocyclohexene, were detected in the vapour phase at both temperatures and for all of the test materials. Their formation was greater on glass and ceramic tiles, compared to other building materials. An empiric Sips isotherm model was employed to approximate experimental results and to estimate the release of lindane and its transformation products. This helped determine the extent of decontamination required to reduce the surface concentrations of lindane to the levels corresponding to vapor concentrations below TWA.

Green building materials are becoming more popular. However, little is known about their ability to support or limit microbial growth. The growth of fungi was evaluated on five building materials. Two green, two conventional building materials and wood as a positive control were selected. The materials were inoculated with Aspergillus versicolor, Cladosporium cladosporioides and Penicillium brevicompactum, in the absence and presence of house dust. Microbial growth was assessed at four different time points by cultivation and determining fungal biomass using the N-acetylhexosaminidase (NAHA) enzyme assay. No clear differences were seen between green and conventional building materials in their susceptibility to support microbial growth. The presence of dust, an external source of nutrients, promoted growth of all the fungal species similarly on green and conventional materials. The results also showed a correlation coefficient ranging from 0.81 to 0.88 between NAHA activity and culturable counts. The results suggest that the growth of microbes on a material surface depends on the availability of organic matter rather than the classification of the material as green or conventional. NAHA activity and culturability correlated well indicating that the two methods used in the experiments gave similar trends for the growth of fungi on material surfaces. © 2014 John Wiley & Sons A/S.

Full Text Available Previous research on the acquisition of tense semantics in child Romanian has demonstrated that typically developing Romanian-speaking three-year-old children have difficulties in the comprehension and production of the imperfect (an imperfective past, and the future (Stoicescu 2013. The present study investigates whether Romanian children have difficulties with the contrasts between the present, the perfect compus (a periphrastic past, and the future. The children obtained high scores for the present in both comprehension and production. In the comprehension of the perfect compus the children performed above chance. In the comprehension and production of the future, the results were significantly lower than chance. The study provides evidence that children have an understanding of the present-past contrasts at this early age, although not at the adult level.

Full Text Available In nowadays, the Phase Change Material (PCM is a viable alternative for reducing the energy consumption and for increase the thermal comfort in buildings. The use of PCM in building applications provides the potential to increase the indoor thermal comfort for occupants due to the reduced indoor temperature fluctuations and lower global energy consumption. The possibility to incorporate the PCM into the material of construction for cooling and heating the buildings gained the interest of researchers from all the world because the PCM have a high heat of fusion, meaning it is capable to storing and release large amounts of energy in the form of heat during its melting and solidifying process at a specific temperature.

Using high-resolution y-rays spectrometry, the natural radioactivity of 14 samples of natural and o manufactured Egyptian building materials have been investigated. The samples were collected from local market and construction sites. From the measured gamma-ray spectra, specific activities were determined. The radium equivalent activity in each sample was estimated. Radiological evaluations of these materials indicate that all materials meet the external gamma-ray dose limitation. Calculation of concentration indices by assuming a Markkanen room model is constructed from these materials, to find the excess gamma-ray dose taken over that received from the outdoors. The Austrian Standard ONORM S 5200 is used in testing the building materials

2014-09-01

Thoron (220Rn) exhalation from building materials has become increasingly recognized as a potential source for radiation exposure in dwellings. However, contrary to radon (220Rn), limited information on thoron exposure is available. The purpose of this study is to develop a test method for the determination of the thoron exhalation rate from building materials. The method is validated, and subsequently the thoron exhalation rates from 10 widely-applied concretes, gypsums, brick, limestone, and mortar are determined. The measured thoron exhalation rates of these materials range from 0.01 Bq m-2 s-1 to 0.43 Bq m-2 s-1, with relative standard uncertainties between 6% to 14%.

2014-08-01

Full Text Available The article discusses the recent international interest in contemporary Romanian art and its growth in market share, with a focus on the United States. The theme is followed thorough in numerous museum exhibitions, increased collector following, art fair presence, gallery representation and auction activity initially in Europe and the United States. The phenomenon is discussed both in the context of the larger international movement conducive to the contemporary art price bubble, and in that of the local socio-economic changes. My chief interest lies in the factors leading up to the entry of post 1989 Romanian art in the global arena as a manifestation of market forces in the field. The analysis follows its grass roots local emergence through non-profit institutions, individual artists, small publications, low budget galleries, as well as the lack of contribution (with few notable exceptions of state institutions, while pointing out the national context of increasing deregulation of social support systems resulting in lack of focus on cultural manifestations. The conclusion is that the recent ascent of contemporary Romanian art (and coincidentally, the award winning contemporary Romanian cinematography is a fortuitous convergence of various factors, among which, increased international mobility and sharing. At the same time, it is also the result of the evolution of various individual artists that pursued a form of art rooted in Romanian artistic tradition but with a focus on the symbolic figurative. The result is a personal semiotics of raising the mundane to extraordinary levels that reconfigured the anxiety of entering a new system into an unmistakable and lasting visual language.

Applying the Dufournaud econometric model to the determination of the prices dynamics impact over the national economy and over its main vulnerable sectors in connection with the Romanian national economy specificity

Full Text Available In economics, a model represents an abstract, formal image of a phenomenon, process or economic system. It is built by symbolically reproducing the economic theory and by getting new information regarding the behavior of the objective being investigated. In economic theory there are several integrated econometric models meant to underline the interdependency between the branches of a national economy by the public utilities services, especially those connected to energy. The present article presents the first results of our efforts of building an econometric model adapted to the specificity of the Romanian economy, that would underline the impact of the prices modification for public utilities on the Romanian economy as a hole, on the competitiveness of Romanian companies and on the inflation.

MEASURING THE INFLUENCE OF THE J-CURVE EFFECT ON TRADE IN ROMANIAN FOREST PRODUCTS

2015-08-01

Full Text Available This paper examines the dynamic effect of the Romanian exchange rate  indices on bilateral trade of Romanian forest products namely fibreboard, particle   board and pulp for paper. Special attention is given to investigate the J-curve hypothesis: whether the trade  balance  for   Romanian   forest   products benefits   from a decline in the  value  of  Romanian Leu (RON. We adopted the autoregressive distributed lag (ARDL approach   to cointegration to estimate the annual bilateral trade data of Romanian forest products  from  1991 to  2013 with various  countries  in the  world. We found  no evidence  of the J-curve  phenomenon for  the  trade in Romanian forest products. The  long-run   analysis   showed the exchange rate  to  be insignificant  in  influencing   the  trade   balance  of  Romanian forest products. This  implies  that  there  are  no changes  in the  trade   balance  for fibreboard, particle board and pulp for paper trade, regardless of whether the Romanian   exchange rate depreciates or appreciates. However, income variables were found to be important factors in determining Romanian trade, only in pulp for paper products.

Natural radioactivity in Slovak construction materials and the indoor dose rate from building materials

International Nuclear Information System (INIS)

Cabanekova, H.; Vladar, M.

1998-01-01

For keeping the population exposure al low as reasonably achievable (recommended by the Slovak regulations), the radioactive content of primordial radionuclides in building materials and products have not to exceed 370 Bq kg -1 of radium equivalent activity and 120 Bq kg -1 of 226 Ra. Samples of building materials (cement, stone, fly-ash, light concrete, slag, dross, sand dolomite. etc.) user for construction of the residential buildings were collected, milled and screened with 2-3 cm sieve. After drying, the samples were stored in 450 cm 3 sealed polyethylene containers for a 30 day period. All samples were measured in a 4 π geometry usually for 60,000 seconds. Measurements of 226 Ra, 232 Th and 40 K concentrations were carried out by high resolution gamma-ray spectrometry. The primordial radionuclides 226 and 232 Th were assessed through their progeny photo-peaks 214 Bi (609 keV), 214 Pb (295 keV, 351 keV) 228 Ac (338 keV, 911 keV) and 212 Pb (238 keV). The specific activity of both nuclides has been determined as weighted average of their photo-peaks. 40 K was measured directly via its 1460 keV peak. Until now, about 600 samples of building materials have been measured. The obtained radium equivalent activity in various types of building materials and mean annual effective doses of gamma radiation are presented. (J.K.)

WOMEN’S AUTONOMY AND THE FAMILY IN RECENT ROMANIAN POLICY-MAKING

Full Text Available In my paper I aim to provide an analysis of the relation between women’s autonomy and the family in Romanian recent policy-making. I will focus primarily on policies developed by the Romanian state after Romania’s integration in the European Union with regards to the family and family-related policy domains. My analysis will focus on several variables: 1. the theoretical instruments available for analyzing women’s autonomy in relation to state policies 2. the understanding of the family in Romanian policy-making 3. the interplay between women’s autonomy and the family and how policy-making influences the relation between the two. The analysis will take into consideration the specific Romanian socio-political context in terms of economic conditions, ideological influences and gender relations. Political theory is no stranger to the issue of individual autonomy. In my paper I will focus on recent feminist political theories on gendered accounts of autonomy. These accounts modify the understanding of autonomy and focus on conditions and aspects of autonomy relevant to women’s lives and experiences. The current financial crisis and recent developments in Romanian policy-making will be analyzed in terms of how they affect women’s autonomy. Since much of Romanian policy-making still avoids including gender and gender relations into its explicit justifications, provisions and evaluation, referring to the family as a basic social unit, the gendered consequences for women’s autonomy of such an approach need to be understood and acknowledged. In my analysis I will use both Romanian and European recent policy papers, as well as recent data obtained through social research.

Concentrations of natural radionuclides of building materials are important in order to estimate exposure of humans to radiation, who can spend up to 80% of their time indoors. One of the indicators of building materials' safety is the radium equivalent activity, which is regulated by national and international normative documents [1,2,3]. Materials with Ra(eq) =stone, red sand, granite, white marble and concrete cubes was performed both before and after ageing of samples (10, 20, 30 and 40 days). Measurement times of samples were 1, 3, 6 and 12 hours. Samples were measured in 1 liter Marinelli beaker geometry, using NaI(Tl) spectrometers with crystal sizes 2.5 x 2.5 in and 3.1 x 3.1 in. Efficiency calibration of spectrometers was done using certified volumetric (1 liter Marinelli beaker) Ra-226, Th-232 and K-40 sources filled with silica sand and density 1,7 kg/l. Herein we present results indicating that one hour measuring may be sufficient for samples in 1 liter Marinelli beakers offering prospect of significant time and cost improvements. References: 1.

Full Text Available Unlike the World War II which brought a series of ideologies, such as Nazism and communism as reasons of outbreak, the World War I used religious themes in its propagandistic message, namely the idea to defend the homeland and faith. Religion was present in the propaganda promoted on the fronts of the Great War, and the military clergy – Catholic, Protestant, and Orthodox – supported it. The military clergy have morally supported the soldiers in the trenches, most of them coming from the peasantry and labor still attached to the Christian values. This study is trying to present the efforts of the Romanian military priests enrolled in the Austro-Hungarian and Romanian armies for spiritually helping the Romanian militaries.

Floating houses “lanting” in Sintang: Assessment on sustainable building materials

Science.gov (United States)

Susanto, D.; Lubis, M. S.

2018-03-01

One important element in the concept of sustainable building is the use of materials. The higher the use of sustainable material in building, the more sustained the building. Lanting is one type of floating construction, usually made from wood, that can be found in settlement along the river, such as in the city of Sintang, West Kalimantan. Lanting is still survive today because it is still used by community whose lives are tied to the river, and also because of its flexible nature that is able to function as a ‘water building’ as well as ‘land building’, and it is also movable, in addition for land limitation in some places. However, the existence of lanting settlements in the city of Sintang faces insistence because it is considered slum, polluting the environment, the scarcity of wooden materials, disturbing the beauty of the city, and threatened by the concretized river banks by local government. This paper discussed the sustainability of waterfront buildings in the city of Sintang in terms of material uses, through the assessment of ‘green-features’ of the main materials used. Assessment results show that wood is the most green building material and lanting is considered at the highest sustainability level for its use of wooden materials.

Moisture measurement in wood, wood-based materials and building materials - a literature review

Kober, A.; Mehlhorn, L.; Plinke, B.

1989-10-01

Methods of moisture measurement in solid substances, especially on wood, wood-based materials and building materials were examined and evaluated according to the literature available. The question was which methods of examining the moisture distribution in building elements at climate loading offer the best accuracy and spatial resolution as well as which methods are the most appropriate at present and in future for the solution of measurement problems in the wood and wood-based industry. The most common methods are electric measurement methods which are utilizing either the moisture-depending conductivity or the dielectric constant or the reflectivity of the material for infrared radiation but they offer only a limited accuracy. The same is valid for the rarely used microwave methods or X-ray and NMR tomography. Simple electric methods will further on play an important role in the industrial process measuring technique. For the examination of building elements, methods using nuclear radiation still offer possibilities for a further development. (orig.) With 207 refs., 13 figs [de

Romania has launched a national research project to promote the use of distributed solar architecture and the use of BIPV systems. These systems include solar tunnels and active solar photovoltaic (PV) systems installed on the roofs and facades of buildings in rural areas. In contrast to other EU states, Romania does not have a photovoltaic building construction branch. The number of isolated cases are insufficient to identify a starting point regarding the PV market in the building industry. The main objective of the project is to demonstrate the efficiency of integrating various PV elements in buildings from rural areas, to test them and to make them known so that they can be used on a large scale. This will be accomplished by installing new products on 2 buildings in Bucharest and in 1 building in Timisoara. The PV modules will be integrated with the architecture. One of the buildings will be a historical building while the other 2 will be new buildings with different typologies. The installed power for each building will be of about 1.000 Wp, including some technologies with PV modules.

Multiscale modelling for better hygrothermal prediction of porous building materials

Directory of Open Access Journals (Sweden)

Belarbi Rafik

2018-01-01

Full Text Available The aim of this work is to understand the influence of the microstructuralgeometric parameters of porous building materials on the mechanisms of coupled heat, air and moisture transfers, in order to predict behavior of the building to control and improve it in its durability. For this a multi-scale approach is implemented. It consists of mastering the dominant physical phenomena and their interactions on the microscopic scale. Followed by a dual-scale modelling, microscopic-macroscopic, of coupled heat, air and moisture transfers that takes into account the intrinsic properties and microstructural topology of the material using X-ray tomography combined with the correlation of 3D images were undertaken. In fact, the hygromorphicbehavior under hydric solicitations was considered. In this context, a model of coupled heat, air and moisture transfer in porous building materials was developed using the periodic homogenization technique. These informations were subsequently implemented in a dynamic computation simulation that model the hygrothermalbehaviourof material at the scale of the envelopes and indoor air quality of building. Results reveals that is essential to consider the local behaviors of materials, but also to be able to measure and quantify the evolution of its properties on a macroscopic scale from the youngest age of the material. In addition, comparisons between experimental and numerical temperature and relative humidity profilesin multilayers wall and in building envelopes were undertaken. Good agreements were observed.

Mold growth in buildings has been shown to be associated with adverse health effects. The fungal and bacterial growth on moistened building materials has been studied, but little attention has been paid to the other organisms spawning in the damaged materials. We examined moist building materials for protozoa, concentrating on amoebae. Material samples (n=124) from moisture-damaged buildings were analyzed for amoebae, fungi, and bacteria. Amoebae were detected in 22% of the samples, and they were found to favor cooccurrence with bacteria and the fungi Acremonium spp., Aspergillus versicolor, Chaetomium spp., and Trichoderma spp. In addition, 11 seriously damaged samples were screened for other protozoa. Ciliates and flagellates were found in almost every sample analyzed. Amoebae are known to host pathogenic bacteria, such as chlamydiae, legionellae, and mycobacteria and they may have a role in the complex of exposure that contributes to the health effects associated with moisture damage in buildings

The diffusion of radon in dwellings is a process determined by the radon concentration gradient across the building material structure and can be a significant contributor to indoor radon inflow. Radon can originate from the deeply buried deposit beneath homes and can migrate to the surface of earth. Radon diffusion and transport through different media is a complex process and is affected by several factors. It is well known that for building construction materials the porosity, permeability and the diffusion coefficient are the parameters, which can quantify the materials capability to hinder the flow of radon soil gas. An increase in porosity will provide more air space within the material for radon to travel, thus reducing its resistance to radon transport. The permeability of material describes its ability to act as a barrier to gas movement when a pressure gradient exists across it and is closely related to the porosity of material. The radon diffusion coefficient of a material quantifies the ability of radon gas to move through it when a concentration gradient is the driving force. This parameter depends upon the porosity and permeability of the medium. As diffusion process is the major contributor to indoor levels, therefore, the factors affecting the diffusion process need to be kept in consideration. Keeping this in mind the experimental arrangements have been made for control study of radon diffusion through some building materials to observe the effects of different factors viz.; compaction, grain size, temperature, humidity and the mixing of these materials etc. For the present study alpha sensitive LR-115 type II solid-state nuclear track detectors (SSNTDs) have been used for the recording of alpha tracks caused by radon gas after its diffusion through the

Full Text Available The aim of the current study was to evaluate the genetic polymorphism of A and B variants at the CSN3 (κ-casein and LGB (β-lactoglobulin loci in Romanian Spotted and Romanian Brown breeds using PCR-RFLP and PCR-HRM genotyping methods. Altogether, 280 cattle from Arad county were genotyped. The most frequent allele at the CSN3 locus was A in Romanian Spotted breed (0.723 while the B allele was the most common in the Romanian Brown (0.694. For LGB locus the A and B alleles recorded similar frequencies for Romanian Spotted (0.5141 and 0.4859 compared to Romanian Brown breed where the B allele was the most prevalent (0.5970. Knowledges regarding genetic information of breeds related to milk protein are valuable for economic reassertion of cattle breeds, particularly autochthonous ones. Further, the results would be useful in future breeding programs for the studied population, aimed to improve cattle genetic structure for milk quality traits.

The Evolution Of Romanian Advertising Agencies Seen By Professional

2013-12-01

Full Text Available This paper aims to present the opinions of Romanian advertisers on the local industry from two viewpoints: the evolution of advertising after 1990 with regards to brand development, and the attempt of advertising agencies to balance change and stability during the economic crisis. Regarding the first aspect, the study emphasizes the way the Romanian market has developed in terms of local and global brands, revealing the most successful brands and campaigns delivered by the local industry and the significance of local brands to advertising professionals. On the ex-communist and new-democratic background, this paper seeks to reveal the way the Romanian identity has been conveyed in advertising in the last 20 years, based on professionals’ experience. In this respect, this article focuses on Romanian brands history after 1990, considering that local economy and capitalism changed consumers’ mentality and needs. It was a time of transition, but the best moment for developing old brands and branding local products, whose image did not even exist before. In terms of strategy, this research shows great interest for this process of surviving and saving domestic brands, not only by adjusting their values to the new-democratic world. The evolution of Romanian advertising is also deeply connected to its identity on the European market, especially to being recognized as a re-born industry after the Communist Era. Regarding the second issue of the present research, the study attempts to uncover whether the internal organization of advertising agencies progressively changed in order to more effectively cater to client needs.

The radioactivity of some building materials used in Thiruvannamalai city has been measured using a NaI(Tl) detector based gamma ray spectrometer. The distribution of natural occurring radionuclides ( 226 Ra, 232 Th and 40 K) in the building materials was studied. The radium equivalent activity (Ra eq ), external hazard index (H ex ) internal radiation hazard index (H in ) and the activity utilization index (I) associated with the natural radionuclide are calculated to assess the radiation hazard of the natural radioactivity in the building materials. The present work shows that the natural radioactivity levels in the building construction materials used in Thiruvannamalai city is well below the acceptable limits. From the analysis, it was found that these materials may be safely used as construction materials and do not pose significant radiation hazards. (author)

A statistics was made of 7128 dwelling-houses considering their age, types of building materials and density of population. Gamma dose rates were measured by means of the TL and pressurized ionization chamber techniques inside 300 buildings and in 44 points outdoors over different kinds of beddings. Personal doses of 49 inhabitants of the buildings monitored were also recorded. By means of the spectrometric analysis of gamma radiation, and basing on a specially developed computational programme ''DOZA'' mean concentrations of 40 K, 226 Ra and 232 Th in 61 samples of building materials were evaluated. It was found that the mean personal dose rate as well as the mean indoor dose rate equals 5.7 urad/h /15.8 pGy/s/ and is about 19% higher than the dose outdoors which equals 4.8 urad/h /13.3 pGy/s/. Gamma dose rates inside the buildings made of gravel-sand concrete elements are about 10% lower than those in the buildings made of red bricks. Mean annual dose equivalent per capita from gamma radiation of building materials equals 40.6 mrem/y /406 uSv/y/, which constitutes about 57% of total annual dose equivalent per capita from all environmental sources of gamma radiation in the residential districts in Krakow.

This article describes the first stage in the history of Romanian astronomy represented by the events, processes and evolution which led to the formation of great scientific personalities, development drives and the creation of the material base for the contemporary Romanian astronomy, having a focus point on the activity of Bucharest Observatory. The article discusses the roots of an evolution pathway determined and inspired by the activity of several scientific personalities of Romania such as Stefan Hepites, Spiru Haret, Nicolae Coculescu and others. It also underlines that a great importance for the astronomical research in Romania was given by the outstanding technical value of the main instruments used at the Observatory in the first decades of activity and, consequentially, by their longevity in service: in the Equatorial Dome - the impressive 6 m. Prin-Mertz telescope and in the Meridian Hall - the GautierPrin telescope. This determined the formation of a powerful astrometry division and a research drive which led over time to important scientific works such as the ultraprecise stellar catalogues developed in Romania at Bucharest Observatory, which were appreciated and awarded nationally and internationally. Therefore, the article includes the moments and the people which determined the success of laying the foundations of the Observatory in 1908 and then having completed the initial scientific infrastructure in 1912 when the construction work was finished, and briefly presents the features, scientific utilisation and outputs of its telescopes, some of the best in the world in their golden years.

Full Text Available In order to bring a solution to the problem of waste foundry sand (WFS in the foundry sector and achieve its reuse, geopolymer building material (as a cementless technology was produced from the WFS for the first time in the literature in this study. The physical and mechanical characteristics of this material were determined. In the first part of the experimental step, the sieve analysis, loose/tight unit weight, and loss of ignition of the WFS were obtained as well as the ultimate analysis. In the second step, the water absorption percentage, porosity, unit weight, and compressive strength tests were conducted on the WFS-based geopolymer specimens activated by chemical binders (sodium hydroxide: NaOH and sodium silicate: Na2SiO3. As the unit weights of all the produced samples were lower than 1.6 g/cm3, they may be considered as lightweight building materials. The minimum compressive strength value for building wall materials was accepted as 2.5 MPa by national standards. In this study, the maximum compressive strength value was measured as 12.3 MPa for the mixture incorporation of 30% Na2SiO3 at the curing temperature of 200°C in 28 days. It was concluded that this geopolymer material is suitable for using as a building wall material.

The specific-activity and radon exhalation rate from 26 building material samples from different areas were measured with high pure germanium (HPGe) gamma spectrometer and activated carbon cartridge. It is shown that the radium content is not completely relevant to radon exhalation rate from some building material. The existing national standards on 'The Limit of Radionuclides in Building Materials' (GB 6566-2001) only present internal exposure index as control target but not for radon exhalation rate; in fact, the radon exhalation rate from building materials is closely nearly related to indoor radon concentration. So we suggest that the radon exhalation control target should be included in the national standards on 'The Limit of Radionuclides in Building Materials'. (authors)

Thermal energy storage (TES) systems using phase change material (PCM) have been recognized as one of the most advanced energy technologies in enhancing the energy efficiency and sustainability of buildings. Now the research is focus on suitable method to incorporate PCMs with building. There are several methods to use phase change materials (PCMs) in thermal energy storage (TES) for different applications. Microencapsulation is one of the well known and advanced technologies for better utilization of PCMs with building parts, such as, wall, roof and floor besides, within the building materials. Phase change materials based microencapsulation for latent heat thermal storage (LHTS) systems for building application offers a challenging option to be employed as effective thermal energy storage and a retrieval device. Since the particular interest in using microencapsulation PCMs for concrete and wall/wallboards, the specific research efforts on both subjects are reviewed separately. This paper presents an overview of the previous research work on microencapsulation technology for thermal energy storage incorporating the phase change materials (PCMs) in the building applications, along with few useful conclusive remarks concluded from the available literature.

Stefanescu Cristina Alexandrina

2012-12-01

Full Text Available International harmonization and convergence of accounting had gradually become one of the most challenging topic of worldwide research and a very hot debated issue in practitioners’ sphere, too. Several studies have addressed both formal and material accounting harmonization along time, a wide range of instruments have been developed and various statistical tools have been used in this respect. Basing on this background, we focused our attention on Romanian banking system which is now experiencing a great challenge by finally entirely adopting IFRS after the first step from 2005 when consolidated financial statements in accordance with IFRS were required and the second one from 2009 when informative individual financial statements under IFRS begun compulsory. Therefore, the objective of our paper is to empirically measure and compare the levels and progress of material accounting harmonization in Romanian banking sector focusing on financial instruments and their related disclosure requirements. First studies conducted in the measurement of harmonization practices (Nair and Frank, 1981; McKinnon and Janell, 1984; Doupnik and Taylor, 1985 started at the beginning of the 80’s, but were merely descriptive, focused on examining how IAS had been adopted in various countries around the world. In the earliest 90’s, there were developed the first instruments for measuring material harmonization, namely the concentration indices (H, C and I Index (Van der Tas, 1988; 1992 and various other forms of these (Archer et al., 1995, which were widely used in various research studies (Herrmann and Thomas, 1995; Aisbitt, 2001; Taplin, 2004. Basing on these measurement tools and cconsidering the main aim of our study – to measure material accounting harmonization in Romanian banking sector – we stated four hypotheses, thus trying to answer our questions: “Are the accounting practices related to financial instruments

Remediating Global Media in Recent Shakespeare Productions on Romanian Stages

Nicolaescu Mădălina

2016-08-01

Full Text Available The paper discusses recent Romanian Shakespeare productions of The Tempest and A Midsummer Night’s Dream in Bucharest. It argues that global mass culture, in the form of TV sitcoms and musicals, YouTube clips and computer games, is re-circulated on Romanian stages with the result of re-mediating the older forms of Romanian Shakespeare performances. The paper interrogates the popular character of the new type of productions, which are largely unpolitical and motivated by commercial reasons. The last part of the paper presents a radical deconstruction of Shakespeare’s text in the form of a computer game, which, however, re-introduces the political orientation of older, pre- 1989 performances.

2017-04-01

Full Text Available This paper aims to present several aspects of the behavior of the Romanian townspeople in the recent years, on the occasion of the winter holidays. I made an indirect research, based on secondary data sources. Many sources I used are from past years. Sometimes, the secondary sources can provide very valuable data at a national level. The most important Romanian holidays are the winter ones (Saint Nicholas, Christmas, New Year's Eve. There are also other winter holidays, but of lesser importance. The Romanians are traditionalists; they cherish the winter holidays and the family. Giving holiday gifts (sweets, clothing, footwear, perfumes, cosmetics, toys to family members and to close relatives is a feature of Romanian townspeople behavior during the main winter holidays. Most Romanian townspeople spend the winter holidays at home or at friends. During the economic crisis, reduction of costs included also the expenses intended for winter holidays. Changes in the behavior of Romanian tourists, due to the economic crisis, included especially the reduction in the number of holidays, the reduction of the duration of the holiday, avoidance of foreign destinations. This paper does not refer to all the aspects of the purchasing behavior or consumption of the Romanians townspeople on the occasion of winter holidays, but only to some aspects.

Jia Peng

2017-06-01

Full Text Available The extensive use of reinforced materials in the construction industry has raised increased concerns about their safety and durability, while corrosion detection of steel materials is becoming increasingly important. For the scientific management, timely repair and health monitoring of construction materials, as well as to ensure construction safety and prevent accidents, this paper investigates corrosion detection on construction materials based on piezoelectric sensors. At present, the commonly used corrosion detection methods include physical and electrochemical methods, but there are shortcomings such as large equipment area, low detection frequency, and complex operation. In this study an improved piezoelectric ultrasonic sensor was designed, which could not only detect the internal defects of buildings while not causing structural damage, but also realize continuous detection and enable qualitative and quantitative assessment. Corrosion detection of reinforced building materials with piezoelectric sensors is quick and accurate, which can find hidden dangers and provide a reliable basis for the safety of the buildings.

2016-10-01

Full Text Available The paper approaches the theme about Anthim the Ivirite is an exponent of Romanian and Caucasian spirituality. Honouring this personality we start from the observation that his spiritual heritage remains relevant over the ages. Some biographers claim that Anthim the Ivirite was from a noble family. His life was as well dramatic, as noble. Anthim the Ivirite remains in Romanian history as a deeply religious man and a man of many talents. He spoke several foreign languages among which Romanian, Greek, Arabic and Turkish. Saint Anthim was a scholar, a printer of religious writings, he wrote religious literature and succeeded to leave a deep mark in the Romanian culture that times undimmed. We consider relevant also that among the important anniversaries of the year 2016 along with the anniversary of Saint Anthim the Ivirite the Romanian Orthodox Church celebrates all the Romanian Church typographers who have contributed fundamentally to a rich religious culture in Romanian. A religious journalist notice for a specialized publication that The fact that the Romanian Orthodox Church, under the clear vision of His Beatitude Patriarch Daniel has chosen to inscribe amongst the paramount holidays of the year 2016 the Church typographers represents a memorable and soul-uplifting gesture, a gesture of conscience in agreement with all who wanted and succeeded to conquer time through the eternity of the typed letter, taking the Word of God in all the four skies and seeding the values of Christian faith and Christian moral in the hearts and thoughts of all Romanians. Posterity’s judgment was warm, respectful and fair in what concerns Saint Hierarch Anthim, and the Holy Synod of the Romanian Orthodox Church glorified him, as a saint and martyr of our Romanian Orthodox Church and this is the reason why the final part of the paper is dedicated to the identification of a string of interesting Anthim anniversaries over the times.

Preservation of adobe buildings. Study of materials

Science.gov (United States)

Velosa, A.; Rocha, F.; Costa, C.; Varum, H.

2012-04-01

Adobe buildings are common in the central region of Portugal due to the lack of natural stone in the surrounding area. This type of construction technique lasted until the 20th Century, at which time cementitious materials, with faster hardening and greater structural capacity substituted traditional materials and techniques. Currently, a significant percentage of these buildings is vacant and many are degraded and in need of conservation actions. Adobes from central Portugal are distinctive as they are lightly coloured and made from air lime and quarry sand. Although some adobes were manufactured locally, most were produced almost 'industrially' and sold to nearby regions. In order to preserve this heritage, conservation actions must be undertaken. So as to ensure the adequacy of these actions and compatibility between original materials and new ones, a thorough study of adobe compostion is mandatory. The current study is an initial step in the characterization of earth based construction materials from central Portugal. Adobe samples were collected from residential buildings in two different locations. The determination of the composition of adobe blocks encompassed the determination of the binder fraction and of their chemical composition and also the particle size analysis of the aggregate. For this purpose FRX analysis, acid dissolution and dry sieving were performed. Methylene blue test was also executed in order to determine the clay fraction. Additionally, the mineral composition of powder samples and oriented samples was performed using XRD analysis in order to determine the clay minerals present in the blocks. As adobe blocks are extremely prone to the action of water the Geelong test was undertaken in order to provide information in terms of durability. It was concluded that air lime was generally used in adobe compositions. However, the clay content varies in adobes from different regions, providing distinct durability characteristics to these materials.

Full Text Available „Geopolitical aspects of Jewish presence in the Romanian Principalities, during the Middle Ages” is probably one of the very few scientific articles about the geopolitical role of Jewish existence in Romanian territory during the last centuries. Few historians dared to deal with this topic, as it was regarded a very delicate issue. The author is the only geographer that managed to show us some geopolitical aspects regarding the immense role of this ethnic group in the political, economical and social life of the Romanian people during the Middle Ages. Based on various sources of information, and expressing all the facts from a geographical point of view, the author offers us an analytic study of the geopolitical role of Jews who had settled in Romanian territory between XIVth and XVIIIth centuries. Interesting facts are revealed regarding the way Romanian ‘voivodes’ came to the throne and the help they received from the Jews.

Gwiazdowski, B.

1983-02-01

Naturally occurring radionuclides in building materials are a source of external and internal radiation exposure to essentially the entire Polish population. The programme of our studies met two main aspects on radioactivity of building materials: Gamma dose rate and radon or alpha potential energy concentration measurements in dwellings of various kinds of structure and materials in both industrial and rural districts of Poland. Gamma dose rate measurements were made in about 2200 dwellings and radon or alpha potential energy concentration measurements - in 750 dwellings. On the basis of these studies the annual effective dose equivalent to the Polish population due to gamma and alpha radiation indoors was estimated to be 0.39 mSv/a and 0.99 mSv/a, respectively. The contribution of external (from gamma) and internal (from alpha) radiation exposure due to naturally occurring radionuclides in building materials to the total radiation exposure of Polish population was assessed to be 3.6 per cent and 34.2 per cent, respectively. Measurements of about 1500 samples of various kinds of building materials and raw materials were made to determine radionuclide concentrations in them. The highest values were obtained in samples of phosphogypsum, fly ash and slag: potassium concentration ranges up to 36 pCi g -1 (a slag sample), radium - up to 17 pCi g -1 (a phosphogypsum sample) and thorium - up to 4 pCi g -1 (a phosphogypsum). On the basis of the results of our studies we came to the conclusion that it was necessary to work out a control system which could protect habitants against enhancement of indoor exposure to ionizing radiation

2017-01-01

Cross-culturally, dead are protected from posthumous negative evaluations by the universal "nil nisi bonum" precept that governs the ethics within the community of mourners. In this study, we set out to test the observance of this injunction against posthumous gossiping in the Romanian public deathscape. Obituaries and other posthumous articles ( N = 1,148) were collected that covered the deaths of 63 celebrities who passed away between 2013 and 2016. Materials were gathered from the digital archives of three Romanian news sources (a news agency, a "quality" newspaper, and a tabloid), published one week after the moment of death. The findings show that 22% of the articles do contain negative evaluations of the deceased. The percentage rises to 36.4% if we restrict the sample to only those celebrities with a controversial anthumous reputation (19 of 63). These results indicate that celebrities are not spared from critical assessments after they pass away.

Cătălina-Felicia Comăneci

2011-12-01

Full Text Available This article purports to analyse the migration phenomenon from an imagological perspective, focusing on the way Romanian immigrants are portrayed in the international press. Although stereotypes are as old as time, they can be harmful in this contemporary age, when spaces and borders have been largely abolished, with negative impact not only on the Romanians living abroad, but also on the ones left in the country, who are unfairly associated with delinquents. The extent of this discrimination wave promoted by both the international and national mass media is alarming and it is important to make a clear distinction between those Romanian intellectuals working abroad and the illegal immigrants of Romanian origin committing crimes abroad.

Among the material properties of building materials, thermal conductivity, the sound absorption coefficient, compressibility, and dynamic stiffness are regarded as important performance requirements since they directly affect the thermal and acoustic properties of the building. This study measured the changes of the thermal and acoustical performances of glass wool that was actually installed for a long time to the outer wall of a building as an insulation material through a comparison with recently produced glass wool. The results showed that the measured thermal conductivities of the old and the new specimens both rise with an increase of temperature, showing quite similar results in both specimens over temperature ranges of (0 – 20 ºC. The noise reduction coefficient decreased by 0.1 in the old specimen and the difference of the compressibilities in both specimens was shown to be 7.32 mm. The dynamic stiffness of the old specimen was found to be 1.28 MN/m3 higher than that of the new specimen.DOI: http://dx.doi.org/10.5755/j01.ms.20.1.3714

VOCs and odors: key factors in selecting `green` building materials?

Energy Technology Data Exchange (ETDEWEB)

Coombs, C. [Steven Winter Associates Inc., Norwalk, CT and Washington DC (United States)

1998-12-01

The current state of knowledge available for selecting building materials on the basis of emissions of volatile organic compounds (VOCs) and odors is reviewed. The significance of VOCs and odors in building materials is related to their role in influencing indoor air quality. As far as toxicity is concerned, many of the VOCs detected in indoor air are relatively inert when considered singly. They are not however, unimportant because in actual fact they are invariably found in mixtures some of which can be toxic. Although knowledge of VOCs is incomplete, it is important to specify ozone-resistant polymeric building products, i.e. those that are chemically stable and inert to oxidation. In addition to VOCs, attention should also be focused on semi-volatile organic compounds (SVOCs) since they are even more persistent than VOCs and tend to offgas for prolonged periods of time. Similarly, it is reasonable to specify low-odor materials. Inclusion of issues related to complex indoor chemistry, less volatile emissions, in addition to VOCs and odor, should in time result in expanded choices of building materials that promote indoor air quality. 16 refs.,2 tabs.

Full Text Available On the Romanian market 23,9% of all accommodation structures are hotels. Among these 4% are belonging to international hotel chains which is a very small percentage. Almost all international hotel chains realized the potential of the market and that is why they intend to increase the number of hotels opened in Romania. Hotel chains attempt to control and dominate the market as result of an extremely dynamic and complex environment. The decision made by a hotel company to carry out its activity in a foreign country and the way to enter into the market can be motivated by many reasons. The paper analysis the presence of international hotel chains on the Romanian hospitality market and the strategies used to enter on the Romanian market compared with the global strategies. The paper used the comparison method to highlight different entry strategies used by international hotel chains when entering a foreign market. For data collection, the main method used was the observation of annual statistical reports with the support of international hotel chains. The first international hotel chain that came in Romania was InterContinental in 1971, but the majority entered on the Romanian market after 2000. In 2012 other chains announced the intension to penetrate this market. The study identifies strategies for penetrating the Romanian market by international hotel chains. The preferred penetration strategy on the Romanian market is management contract followed by franchise. Not least are highlighted comparative aspects of internationalization decisions taken by the chains in the world and in Romania, analyzing whether in Romania are predominantly used the same strategy as in most other countries or some specific strategies. International hotel companies want to entre on the Romanian market because they consider that in this area is need for hotels which belong to the luxury segment but also hotels that belong to the economy segment.

Pinkard, Andrew; Champsaur, Anouck M; Roy, Xavier

2018-04-17

The programmed assembly of nanoscale building blocks into multicomponent hierarchical structures is a powerful strategy for the bottom-up construction of functional materials. To develop this concept, our team has explored the use of molecular clusters as superatomic building blocks to fabricate new classes of materials. The library of molecular clusters is rich with exciting properties, including diverse functionalization, redox activity, and magnetic ordering, so the resulting cluster-assembled solids, which we term superatomic crystals (SACs), hold the promise of high tunability, atomic precision, and robust architectures among a diverse range of other material properties. Molecular clusters have only seldom been used as precursors for functional materials. Our team has been at the forefront of new developments in this exciting research area, and this Account focuses on our progress toward designing materials from cluster-based precursors. In particular, this Account discusses (1) the design and synthesis of molecular cluster superatomic building blocks, (2) their self-assembly into SACs, and (3) their resulting collective properties. The set of molecular clusters discussed herein is diverse, with different cluster cores and ligand arrangements to create an impressive array of solids. The cluster cores include octahedral M 6 E 8 and cubane M 4 E 4 (M = metal; E = chalcogen), which are typically passivated by a shell of supporting ligands, a feature upon which we have expanded upon by designing and synthesizing more exotic ligands that can be used to direct solid-state assembly. Building from this library, we have designed whole families of binary SACs where the building blocks are held together through electrostatic, covalent, or van der Waals interactions. Using single-crystal X-ray diffraction (SCXRD) to determine the atomic structure, a remarkable range of compositional variability is accessible. We can also use this technique, in tandem with vibrational

Application of Nanotechnology-Based Thermal Insulation Materials in Building Construction

Directory of Open Access Journals (Sweden)

Bozsaky David

2016-03-01

Full Text Available Nanotechnology-based materials have previously been used by space research, pharmaceuticals and electronics, but in the last decade several nanotechnology-based thermal insulation materials have appeared in building industry. Nowadays they only feature in a narrow range of practice, but they offer many potential applications. These options are unknown to most architects, who may simply be afraid of these materials owing to the incomplete and often contradictory special literature. Therefore, they are distrustful and prefer to apply the usual and conventional technologies. This article is intended to provide basic information about nanotechnology-based thermal insulation materials for designers. It describes their most important material properties, functional principles, applications, and potential usage options in building construction.

Radioactivity in building materials : a first overview of the European scenario

International Nuclear Information System (INIS)

Trevisi, Rosabianca; D'Alessandro, Marco; Nuccetelli, Cristina; Risica, Serena

2008-01-01

With a wide research into the national and international literature an inventory was created of building materials in Europe, characterised on the basis of activity concentration of the main natural radionuclides ( 226 Ra, 232 Th and 40 K). Materials of natural origin and containing industrial by-products were both accounted for. The inventory allowed to calculate the activity concentration index I - suggested by a European technical guidance document - for many building materials in Europe. A first identification of materials was thus made, which could be subject to controls or restrictions as for movement and/or use if the index were to be adopted by the European legislation. The analysis presented in this paper is a first attempt to discuss the data of our inventory and only five materials have been analysed. In a near future a more complete discussion will be published, also considering natural stones and superficial materials. As regards natural stones a tentative grouping will be made, classifying stones by their geological origin. Moreover, if enough data were available, we will also assess the radiation protection consequences of the potential use of by-products of industrial origin in building materials. Finally, the activity concentration of 232 Th, often higher than that of 226 Ra, in building materials shows the need of improving research into the health effects of the 232 Th chain, in particular of thoron concentration indoors.

Ciochină, Laura; Faria, Luísa

2009-11-01

This article presents the results of a series of preliminary comparisons, between the Portuguese and Romanian cultural contexts, on the individualism-collectivism (IND/COL) cultural dimension. The IND/COL was evaluated with the Individualism-Collectivism Questionnaire - ICQ -, constructed in New Zealand by Shulruf, Hattie and Dixon (2003, Anonymous Questionnaire of Self-Attitudes - AQSA), and adapted to the Portuguese and Romanian contexts by Ciochină and Faria (2007), using studies of confirmatory factor analysis. The ICQ composed by 26 items, 15 evaluating the IND scale--with three subscales (Uniqueness, Competition and Responsibility)--, and 11 evaluating the COL scale--with two subscales (Harmony and Advice)--, was administered to 395 subjects, 200 Portuguese and 195 Romanian, 10th and 12th graders. On the whole, in the Portuguese and Romanian samples, the multivariate and univariate statistical analyses evidenced the existence of two independent variables--gender and cultural context--, with significant effects, main and of interaction, on the scales and subscales of the ICQ. The results were discussed taking into consideration the specificities of the educational systems in the two cultural contexts, which are inevitably shaped by socio-cultural factors characteristic of the two countries considered in the present study--Portugal and Romania.

Significant portion of the background radiation is coming from the primordial nuclides such as 226 Ra, 232 Th and 40 K which are present in the soil, rock and building material. These radionuclides are sources of the external and the internal radiation exposures in dwellings. The specific activities of 226 Ra, 232 Th and 40 K in the building raw materials and products mainly depend on geological and geographical conditions as well as geochemical characteristics of those materials. Knowledge of radioactivity present in building materials enables one to assess any possible radiological risk to human health

Strategic Use of English in Online Romanian Banking Advertising

Full Text Available The focus on the present paper is on the strategic use of terms, expressions of English origin (anglicisms in the process of advertising certain banking services on the online Romanian banking market. The reasons for the presence of English terms can vary from necessity in the case when a term is too international so as not to be mentioned in the respective advertising message to the touch of prestige that a term/expression can give to the content in which they appear. Although it may seem a very ambitious objective, taking into account the fact that this issue has been far too little tackled upon, by means of this article we are trying to raise awareness of the impact that the presence (or in some cases the abundance of such English terms may ultimately have upon (Romanian bank clients as well as to offer variants of translation of several banking anglicisms that have “comfortable” Romanian correspondents. The theoretical background of our research is supported by a large number of Romanian banking advertising messages that can be found on the websites of the respective banks. In order to obtain the “pulse” of the bank customer market we have chosen to survey 200 1st year students within the Bucharest University of Economic Studies on the use of English terms in online advertisements of student programmes and bank cards offered by nine important banks in Romania. Ultimately, we think that the great merit of our research is that it manages to signal and study the subliminal and very delicate, but potentially beneficial connection between Romanian banking businesses and the linguistic implications of their online advertising messages containing English terms/expressions.

The research outcomes suggest a correlation between the bank’s financial performance, the internationalization process and the CSR multiplication effects for the public perceptions, generating an emotional form of CSR, as a way to strengthen the bank’s reputational value.

ICAN Computer Code Adapted for Building Materials

Science.gov (United States)

Murthy, Pappu L. N.

1997-01-01

The NASA Lewis Research Center has been involved in developing composite micromechanics and macromechanics theories over the last three decades. These activities have resulted in several composite mechanics theories and structural analysis codes whose applications range from material behavior design and analysis to structural component response. One of these computer codes, the Integrated Composite Analyzer (ICAN), is designed primarily to address issues related to designing polymer matrix composites and predicting their properties - including hygral, thermal, and mechanical load effects. Recently, under a cost-sharing cooperative agreement with a Fortune 500 corporation, Master Builders Inc., ICAN was adapted to analyze building materials. The high costs and technical difficulties involved with the fabrication of continuous-fiber-reinforced composites sometimes limit their use. Particulate-reinforced composites can be thought of as a viable alternative. They are as easily processed to near-net shape as monolithic materials, yet have the improved stiffness, strength, and fracture toughness that is characteristic of continuous-fiber-reinforced composites. For example, particlereinforced metal-matrix composites show great potential for a variety of automotive applications, such as disk brake rotors, connecting rods, cylinder liners, and other hightemperature applications. Building materials, such as concrete, can be thought of as one of the oldest materials in this category of multiphase, particle-reinforced materials. The adaptation of ICAN to analyze particle-reinforced composite materials involved the development of new micromechanics-based theories. A derivative of the ICAN code, ICAN/PART, was developed and delivered to Master Builders Inc. as a part of the cooperative activity.

The results of the specific activities of {sup 232}Th, {sup 226}Ra and {sup 40}K measured in samples of commonly used building materials in Bosnia and Herzegovina are presented. Measurements were performed by gamma-ray spectrometer with coaxial HPGe detector. The surface radon exhalation and mass exhalation rates for selected building materials were also measured. The determined values of specific activities were in range from 3.16 ± 0.81 Bq kg{sup -1} to 64.79 ± 6.16 Bq kg{sup -1} for {sup 232}Th, from 2.46 ± 0.95 Bq kg{sup -1} to 53.89 ± 3.67 Bq kg{sup -1} for {sup 226}Ra and from 28.44 ± 7.28 Bq kg{sup -1} to 557.30 ± 93.38 Bq kg{sup -1} for {sup 40}K. The radium equivalent activity, the activity concentration index, the external and internal hazard indices as well as the absorbed dose rate in indoor air and the corresponding annual effective dose, due to gamma-ray emission from the radioactive nuclides in the building material, were evaluated in order to assess the radiation hazards for people. The measured specific activities of the natural radioactive nuclides in all investigated building materials were compared with the published results for building materials from other European countries. It can be noted that the results from this study are similar to the data for building materials from neighbouring countries and for building materials used in the EU Member States. The radiological hazard parameters of the building materials were all within the recommended limits for safety use.

On 18 May 2001, in the presence of Mr. Adrian Nastase, the Prime-Minister of Romania, the presidents of AECL, ANSALDO and Director General of SN Nuclearelectrica, the commercial and management contract for completing the Cernavoda NPP Unit 2 was signed. This document stipulates the goal and the partners' commitments, leadership organization, the SN Nuclearelectrica's control of the Budget, costs for the technical assistance (around 180 specialists from abroad), as well as the costs of equipment supplied from Canada and Italy. Services and equipment supplied by Canada and Italy amounts up to around USD 300 millions. Efforts are currently undertaken to obtain a loan of USD 300 millions from EURATOM, beginning from 2003. An auction process, implying around 10 companies, is underway and by the completion of the process, in February 2002, the practical delivery of equipment will start. The so-far invested capital amounts around USD 650 millions while the capital funds remaining to be invested amounts up to about USD 689 millions. From the latter figure, around USD 100 millions represent the costs for heavy water and the initial nuclear fuel charging. The personnel dynamics is presented as well as problems relating with recruitment and salary policy. Romanian nuclear industry is engaged for supply of a series of important components. General Turbo SA, supplied already components of some tens USD millions for the turbogenerator complex. PETROTUB company from Roman, Romania supplied already one thousand tones of non-nuclear carbon steel tubing valued at about USD 300 millions. ARIO, Bistrita, Romania, has signed contracts valued at about USD 400,000 for non-nuclear reinforcing materials. Other companies like AVERSA SA and Ventilatorul SA supplied reliable equipment for Unit 1 and will continue to do the same for Unit 2.

RESRAD-BUILD: A computer model for analyzing the radiological doses resulting from the remediation and occupancy of buildings contaminated with radioactive material

International Nuclear Information System (INIS)

Yu, C.; LePoire, D.J.; Jones, L.G.

1994-11-01

The RESRAD-BUILD computer code is a pathway analysis model designed to evaluate the potential radiological dose incurred by an individual who works or lives in a building contaminated with radioactive material. The transport of radioactive material inside the building from one compartment to another is calculated with an indoor air quality model. The air quality model considers the transport of radioactive dust particulates and radon progeny due to air exchange, deposition and resuspension, and radioactive decay and ingrowth. A single run of the RESRAD-BUILD code can model a building with up to: three compartments, 10 distinct source geometries, and 10 receptor locations. A shielding material can be specified between each source-receptor pair for external gamma dose calculations. Six exposure pathways are considered in the RESRAD-BUILD code: (1) external exposure directly from the source; (2) external exposure to materials deposited on the floor; (3) external exposure due to air submersion; (4) inhalation of airborne radioactive particulates; (5) inhalation of aerosol indoor radon progeny; and (6) inadvertent ingestion of radioactive material, either directly from the sources or from materials deposited on the surfaces of the building compartments

Full text: Based of the Romanian option to develop and operate nuclear facilities, using as model the networks created at European level and taking into account the international importance of the structural integrity assessments for lifetime extension of the nuclear components, a national Project started since 2005 in the framework of the National Program 'Research of Excellence', Modulus I 2006-2008, managed by the Ministry of Education and Research. Entitled 'Integrated Network for Structural Integrity Monitoring of Critical Components in Nuclear Facilities', with the acronym RIMIS, the Project had two main objectives: - to elaborate a procedure applicable to the structural integrity assessment of the critical components used in Romanian nuclear facilities; - to integrate the national networking in a similar one, at European level, to enhance the scientific significance of Romanian R and D organizations as well as to increase the contribution to solving one of the major issue of the nuclear field. The paper aimed to present the activities performed in the Romanian institutes, involved in the Project, the final results obtained as part of the R and D activities, including experimental, theoretical and modeling ones regarding structural integrity assessment of nuclear components employed in CANDU type reactors. Also the activity carried out in the framework of the NULIFE network, created at European level of the FP6 Program and sustained by the RIMIS network will be described. (authors)

Natural radioactivity and associated radiation hazards in building materials used in Peloponnese, Greece

2008-01-01

Five different kinds of building materials (Pozzolanic and Portland cements, limestone, white cement, marble powder and sand) commonly used in building construction in Peloponnese, Greece, and Portland cement's raw materials were analyzed for their natural radioactivity content, using γ-ray spectrometry. Pozzolanic and Portland cement (Cem II) samples were found to contain the highest average 226 Ra, 232 Th and 40 K activity concentrations compared with the other examined building material samples. This could be attributed to their containing fly ash, which was found to contain high natural radionuclide concentrations, especially that of 226 Ra (1041Bqkg -1 ). Results obtained were compared with the results reported by other Greek researchers and the worldwide values for building materials and soil. The calculated activity concentration index (I) values for all the examined building material samples were lower than the recommended exception limits for exposure to external γ-radiation

Valorisation of phosphogypsum as building material: Radiological aspects

Tayibi, H.

2011-12-01

Full Text Available Nowadays, alternative uses of phosphogypsum (PG in the building industry are being considered in several countries; however, the natural radioactivity level in the PG could be a restriction for those uses. United States Environmental Protection Agency (US-EPA classified PG as Technologically Enhanced Naturally Occurring Radioactive Material (TENORM. This drawback could be avoided controlling its percentage in the cement preparation and the radionuclides content in the other raw materials used in its production, and calculating the activity concentration index (I in the final by-products. The valorization of PG as a building material has been studied, from a radiological point of view, by developing a new stabilisation/solidification process. PG is incorporated within a polymeric sulphur matrix, obtaining a concrete-like material, which presents lower natural radioactive content than the initial PG. The 226Ra content of this material ranged between 26-27 Bq·kg-1 and it is quite similar to that of common Spanish building materials.

Actualmente, en muchos países se está contemplando el uso alternativo del fosfoyeso (PG en la industria de la construcción, aunque su contenido en radionucleidos naturales puede presentar ciertas restricciones para dicha aplicación (material clasificado por la US-EPA como TENORM: “Technologically Enhanced Naturally Occurring Materials. No obstante, estos inconvenientes podrían paliarse controlando el porcentaje del PG y los niveles de radioactividad en las materias primas a incorporar al cemento y calculando el índice de concentración de actividad (I en los productos finales. La valorización del PG como material de construcción se ha estudiado en este trabajo desde el punto de vista radiológico, desarrollando un nuevo proceso de estabilización/solidificación, obteniéndose un material de características similares al cemento y que presenta menor contenido de radionucleidos naturales que el

Full Text Available This study tries, although we are aware of its limits, to offer two methods through which Romanian democracy could overcome its state of „non-development”. Beyond the objective and the subjective causes of the democratic backwardness of Romania, causes that have been discussed both in the academic community and in the public space, we think that it might be more relevant to identify the possibilities of an evolution. Although omnipresent in the Romanian public debate, the two ways to follow are approached from a special perspective, following a certain liberal model, stressing the importance of protecting the individual interests and rights of the citizens against the inherent abuses of the institutions of the political power..

SELF-REFERENTIALITY AND INTER-REFERENTIALITY IN ROMANIAN CULTURAL ANTHROPOLOGY (1964–2012

2014-05-01

Full Text Available The bibliographic retrospective of the practice of cultural anthropology in Romania is significant for the actuality of a process of changing and renewing the scientific interest and the inquest “field” of Romanian researchers. More precisely, the self-referential or “intra-cultural” knowledge about Romanian communities or groups of population currently appears to be turned into a inter-referential knowledge, with a cross-cultural content. It is through such theoretical and methodological metamorphosis that the study of minority ethno-linguistic communities in Romania takes part to a contextualized understanding of Romanian cultural identities in relation to the groups of Magyars, Germans, Roma, Russian-speaking Lipovans, Turks, Croatians etc. As a result, my text attempts to evaluate the inner dynamics of Romanian cultural anthropology in terms of a critical synthesis of the local specialized literature, in the context of anthropological disciplinary evolution in Central and Southeastern Europe

Football and Romanian Masculinity. How it is constructed by the Sport Media?

Directory of Open Access Journals (Sweden)

Péter László

2017-12-01

Full Text Available The present article is focusing on hegemonic masculinity represented and expressed by the professional footballers. Based on the empirical study using text analysis of leading articles published in central Romanian sport newspapers I draw the ideal-typical picture of the normative model of Romanian hegemonic masculinity in which the domestic coaches play a determinant role. Their personal-individual and collective-professional features like determination, steadiness, honesty, pride, mutual respect, knowledge, tenaciousness, sense of vocation, solidarity, spirit of fighting are the corner points of the constructed Romanian manhood, or hegemonic masculinity during social change. The manliness is traced along the inner characteristic of the coaches but in strong contradiction with the foreign trainers. In this respect I can state that football is connected not only with masculinity but in some respect also with the national characteristics embodied by the Romanian coaches especially those working home.

In Romania, three main NGOs act in promoting peaceful use of nuclear energy. The organization with the longest road is the Romanian Association for Nuclear Energy (AREN), created by individual persons acting in nuclear field in 1990. In 2001, a number of Romanian and foreign legal entities having core competence or unfolding nuclear energy related industrial and research activities created the Romanian Industrial Forum (Romatom). Both AREN and Romatom are active parts of European nuclear world: AREN is European Nuclear Society member and Romatom is Foratom member. The 3rd NGO is Women in Nuclear Romania (WiNRo) which registered in 2011. However, the women acting in nuclear field have become earlier active independent voices particularly in public communication on nuclear field matters. The debut was in 1993 when the women group acting in AREN became members of WiN Global, the organization that they trust would become a real opportunity to share their professional competences and improve their communication knowledge and skills in the light of the mission they decided to embrace, namely, that of clear, transparent and trustful communication with stakeholders, particularly the general public on peaceful use of nuclear energy. Today, WiN Ro is also part of WiN Europe where common European desiderates aim to establish and achieve. Today, Romanian NGOs act to continue the trustful relations they have built with a large portfolio of stakeholders adapting their endeavors for answering to various stakeholders needs for transparency and effective communication on nuclear matters at national level. At international level, the Romanian NGOs aim to register benefic experience for their organizational works and opportunities for promotion of the national good approaches, from relations with stakeholders acting in the international arena of nuclear world. Relevant aspects on how the Romanian NGOs have approached relations with stakeholders will be presented. (author)

Gharbi, F; Oueslati, M; Abdelli, W; Samaali, M; Ben Tekaya, M

2012-12-01

Building materials can expose public and workers to radiation because of their content of radium, thorium and potassium isotopes. This is why it is very important from the radiological point of view to survey the natural radioactivity content of commonly used building materials in any country. This work consists of the measurement of (226)Ra, (232)Th and (40)K activity concentrations in a variety of commonly used building materials in Tunisia and on the estimation of their radiological hazard. The maximum value of radium equivalent for the studied materials was equal to 169 Bq kg(-1) and corresponds to the clay brick, which is lower than the recommended value of 370 Bq kg(-1). In this work, several radiological indexes were calculated and were found to be under their highest permitted limit.

Full Text Available Aim: The objective of this study was to assess the behaviors with risk for road traffic injuries among Romanian young people. Material and Method: Self-administered questionnaires were completed by the study sample consisting of 1598 junior high school students, senior high school students and university students aged 11-24 years from both urban and rural areas of two counties (Cluj and Hunedora of Romania. Results: The results show that around 80% of the junior high school students and more than 90% of the senior high school students and university students who go by bike do not wear helmets or use them rarely when they are cycling. Seatbelts are used more frequently than the helmets, but still more than one third of the junior high school students and senior high school students and a quarter of the university students do not use seatbelts or use them rarely. In the month previous the survey around one quarter of the students travelled in a car whose driver used alcohol before driving. Moreover, 15% of the university students who drove recognized that, at least once during their life, they did this after they used alcohol. Conclusions: The results indicate that comprehensive actions must be developed in order to prevent road traffic injuries among Romanian young people. They must include educational programs for youngsters and parents as well as adoption and enforcement of legislative measures and technical actions, which promote road safety.

Biological treatment using methane-oxidizing bacteria (MOB) immobilized on six porous carrier materials have been used to mitigate methane emission. Experiments were performed with different MOB inoculated in building materials at high (~20 % (v/v)) and low (~100 ppmv) methane mixing ratios. Methylocystis parvus in autoclaved aerated concrete (AAC) exhibited the highest methane removal rate at high (28.5 ± 3.8 μg CH₄ g⁻¹ building material h⁻¹) and low (1.7 ± 0.4 μg CH₄ g⁻¹ building material h⁻¹) methane mixing ratio. Due to the higher volume of pores with diameter >5 μm compared to other materials tested, AAC was able to adsorb more bacteria which might explain for the higher methane removal observed. The total methane and carbon dioxide-carbon in the headspace was decreased for 65.2 ± 10.9 % when M. parvus in Ytong was incubated for 100 h. This study showed that immobilized MOB on building materials could be used to remove methane from the air and also act as carbon sink.

ROMANIAN TEXTILES AND CLOTHING INDUSTRY – PRESENT AND PERSPECTIVES

Directory of Open Access Journals (Sweden)

Ovidiu FOLCUT

2009-12-01

Full Text Available In January 2007 Romania joined the EU. Since then its current import duties for clothing and textiles has dropped a full 10% to between 6% and 8%. Consequently, import and re-export opportunities for Hong Kong, the Chinese mainland and other Asian suppliers are expected to increase, according to local Romanian importers. Chinese mainland firms are said to have invested US$254 million in the Romanian economy, but no details are available about the proportion directly invested in the clothing and textile sectors. Romania is now a lesser force in the garment and textile industry than it used to be, where it comes to feeding the EU market - even though the country is still the largest producer of such goods in Central and Eastern Europe, ahead of comparable economies such as Ukraine and Bulgaria. Romania also easily outcompetes more expensive labour in Hungary and Poland, neither of which are now considered contenders for price-sensitive trades, say Romanian analysts.

INTEGRATING UNMANNED AIRCRAFT VEHICLES IN THE ROMANIAN NATIONAL AIRSPACE

Sorana Alina Catinca POP

2015-07-01

Full Text Available The use of unmanned aerial vehicles in the Romanian civil airspace brings us back to the 1920's, when the first aircraft started to fly over the Romanian sky. Little did the legislators at that time know how to create the proper legal framework for the use of such machines so that all aspects related to their use be covered, as well as identify all potential risks and effects. Nowadays, UAVs are the new aircraft and it is a challenge for the legislators to properly identify the legal framework so that the safety and security of civil aviation are not affected. The paper will address the challenges the regulator faces in the integration of the UAVs in the Romanian civil airspace, developments and issues raised by the current regulation, as well as aspects related to the national regulations expected to enter into force at the end of 2015, beginning of 2016.

Five different kinds of building materials (Pozzolanic and Portland cements, limestone, white cement, marble powder and sand) commonly used in building construction in Peloponnese, Greece, and Portland cement's raw materials were analyzed for their natural radioactivity content, using {gamma}-ray spectrometry. Pozzolanic and Portland cement (Cem II) samples were found to contain the highest average {sup 226}Ra, {sup 232}Th and {sup 40}K activity concentrations compared with the other examined building material samples. This could be attributed to their containing fly ash, which was found to contain high natural radionuclide concentrations, especially that of {sup 226}Ra (1041Bqkg{sup -1}). Results obtained were compared with the results reported by other Greek researchers and the worldwide values for building materials and soil. The calculated activity concentration index (I) values for all the examined building material samples were lower than the recommended exception limits for exposure to external {gamma}-radiation.

Internal exposure to alpha particles emitted from 222 Rn (radon) and its daughters is the second leading cause of lung cancer. As a source of indoor radon in home, there are interior building materials that contain radioactive minerals. These radioactive consumer products have been claimed by distributors to have effect of 'minus-ion' or 'radon spring' for healthy promotion. We analyzed radioactive nuclides contained in the interior building materials, and measured radon levels released from them. The results of gamma-ray spectrometry revealed that these interior building materials contain U- and Th-series nuclides. The densities of some radioactive nuclides in the tile used for a bathroom exceeded the exempt limits of International Basic Safety Standards. However, the radon densities released from the tile was lower than detectable limit. In contrast, one of the wallpaper released 34 Bq·m -3 of radon gas in a 50-liter container. This value is two times higher than the average radon level in Japanese homes. The minus-ion effect' wallpapers are thought to be a cause of residential exposure to radon. (author)

Study of radiation dose reduction of buildings of different sizes and materials

Furuta, Takuya; Takahashi, Fumiaki

2015-01-01

The dependence of radiation dose reduction on the sizes and materials of buildings was studied by numerical analyses using the Monte Carlo simulation code, PHITS. The dose rates inside the buildings were calculated by simulating gamma-ray transport from radioactive cesium deposited at the ground surface. Three building models were developed: the wooden house, the open-space concrete building, and the thin-wall building, to study the effect of building size and construction material on dose reduction inside these structures. Here the floor-area sizes of the building models were varied to clarify the influence of building configuration on dose reduction. The results demonstrated that the dose rates inside the buildings linearly decreased with increasing floor area on a logarithmic scale for all types of buildings considered. The calculated dose distribution inside a building indicated that the distance from the outer walls was a determining factor for the dose rate at each position in the building. The obtained tendency was verified by comparison with data reflecting the dose reduction of typical buildings in Japan. (author)

The Institute for Nuclear Research (ICN), a subsidiary of Romanian Authority for Nuclear Activities, at Pitesti - Romania, has developed a preliminary design of a fuel bundle with 43 elements named SEU 43 for high burnup in CANDU Reactor. A very high experience in nuclear fuels manufacturing and control has also been accumulated. Additionally, on the nuclear site Pitesti there is the Nuclear Fuel Plant (NFP) qualified to manufacturing CANDU 6 type fuel, the main fuel supplier for NPP Cernavoda. A very good collaboration of ICN with NFP can lead to a low cost upgrading the facilities which ensure at present the CANDU standard fuel fabrication to be able of manufacturing also SEU 43 fuel for extended burnup. The financial founds are allocated by Romanian Authority for Nuclear Activities of the Ministry of Industry and Resources to sustain the departmental R and D program 'Nuclear Fuel'. This Program has the main objective to establish a technology for manufacturing a new CANDU fuel type destined for extended burnup. It is studied the possibility to use the Recovered Uranium (RU) resulted from LWR spent fuel reprocessing facility existing in stockpiles. The International Agency for Atomic Energy (IAEA) sustains also this program. By ROM/4/025/ Model Project, IAEA helps ICN to solve the problems regarding materials (RU, Zircaloy 4 tubes) purchasing, devices' upgrading and personnel training. The paper presents the main actions needing to be create the technical base for SEU 43 fuel bundle manufacturing. First step, the technological experiments and experimental fuel element manufacturing, will be accomplished in ICN installations. Second step, the industrial scale, need thorough studies for each installation from NFP to determine tools and technology modification imposed by the new CANDU fuel bundle manufacturing. All modifications must be done such as to the NFP, standard CANDU and SEU fuel bundles to be manufactured alternatively. (author)

A study has been carried out to determine the natural radioactive content of building materials used in Malaysia. The materials analysed include both old and new clay bricks, cement bricks, mortar, cement, sands, ceramic tiles and gypsum. Samples of the first three materials were collected from the 12 states of the Malay Peninsula. Radium-226 (from the U-238 series) and Ra-228 (from the Th-232 series), these both representing naturally occurring radionuclides, were analysed using high-resolution HpGe gamma spectrometers. The results of our investigations showed that some old clay bricks contain high levels (at more than 5 times the normal soil concentration) of natural radionuclides, with maximum concentrations of 590 Bq/kg and 480 Bq/kg for respectively Ra-226 and Ra-228. The reasons behind this finding were not clearly understood. As there are people living in old buildings, i.e. built using old clay bricks, there is a possibility that they are being exposed to significant radiation doses. However, there proved to be no significant overall difference between old and new clay bricks in terms of the natural radioactivity levels determined, at a 95% confidence level. The overall mean concentrations of Ra-226 and Ra-228 observed in Malaysian clay bricks were respectively 118 {+-} 58 Bq/kg and 120 {+-} 42 Bq/kg. The radioactive content of other materials was found to be not much different from that to be determined in normal soil from Malaysia. The data obtained can be used as a basis for reaching decisions on the regulatory limits for radioactivity levels in building materials in Malaysia. (orig.)

Exposure to radiation from the natural radioactivity in building materials

International Nuclear Information System (INIS)

1979-05-01

Radiation exposure of members of the public can be increased appreciably by the use of building materials containing above-normal levels of natural radioactivity. This phenomenon has attracted attention in recent years, and in this review, an attempt is made to the quantify exposures incurred under various circumstances. The second section of the review is a general survey of those building materials, mostly industrial wastes, that have aroused interest in Member countries. The probability that environmental pressures may cause such wastes to be used more and more by building industries may lead to similar situations in the future. Other review material of a relevant nature is described in the third section. Primordial radionuclides only are considered here. They are: potassium-40 (K-40); radium-226 (Ra-226) and its decay products; the series headed by thorium-232 (Th-232). The important radiological consequences of the natural radioactivity in building materials are two-fold, irradiation of the body by gamma rays and irradiation of the lung tissues by radon-222 (Rn-222) decay products or daughters. These consequences cannot be explored quantitatively except in relation to the specific activities of the nuclides of interest, and the approach adopted in this review is to assess the consequences in terms of the incremental radiation exposures that would be incurred by occupants of substantial dwellings entirely constructed of materials with various specific activities or combinations thereof. Gamma rays are dealt with in the fourth section and radon daughters in the fifth

The article describes the current state of knowledge and practice in Poland concerning recycling as a method of reuse of chosen groups of waste materials in building industry. The recycling of building scraps is imposed by environmental, economic and technological premises. The issue of usage of sewage residues is becoming a problem of ever -growing gravity as the presence of the increasing number of pernicious contaminants makes their utilization for agricultural purposes more and more limited. The strategies of using waste materials on Polish building sites were analyzed. The analysis of predispositions to salvage for a group of traditional materials, such as: timber, steel, building debris, insulation materials, plastics, and on the example of new materials, such as: artificial light aggregates made by appropriate mixing of siliceous aggregates, glass refuses and sewage residues in order to obtain a commodity which is apt for economic usage also was made in the article. The issue of recycling of waste materials originating from building operations will be presented in the context of the binding home and EU legal regulations. It was proved that the level of recycling of building wastes in Poland is considerably different from one which is achieved in the solid market economies, both in quantity and in assortment. The method of neutralization of building refuses in connection with special waste materials, which are sewage sludge that is presented in the article may be one of the alternative solutions to the problem of recycling of these wastes not only on the Polish scale.

Background: With the rapidly economic development and urbanization in Yan'an city, more building materials were consumed in building construction. While the natural radioactivity level of building materials from Yan'an is limited in the literatures. Purpose: The main objective of this study is to determine the natural radioactivity level and to analyze the associated radiation hazards of building materials in Yan'an. Methods: The specific activities of natural radionuclides 226 Ra, 232 Th and 40 K in various building materials from Yan'an city were determined using low-background gamma-ray spectrometry, and their radiation hazards were evaluated according to the standard methods. Results: The results show that the specific activities of 226 Ra, 232 Th and 40 K in the building materials are 9.4-73.1, 11.5-86.9 and 258.9-1055.1 Bq/kg, respectively. The activities of 226 Ra and 232 Th, except for sand and gravel aggregate, in all other building materials are higher than the corresponding means of local soil, and the activities of 40 K in hollow brick, red-clay brick, sand and gravel aggregate exceed the means of 40 K in soil. However, the values of internal exposure index, external exposure index and gamma radiation index in all investigated building materials are less than 1. Conclusions: The radiation levels of all analyzed building materials are within the national safety standard, which indicates that all analyzed building materials can be used anywhere and they can't cause radiation hazard to the local residents.

Full Text Available The research question is the relationship between the local community and globalization tendencies and transformation or maintenance of local traditions. The research area is a specific locality of a Czech village in Romanian Banat. The local community has evolved in a relative isolation. Agriculture was the most important activity despite the fact that a mining factory was opened there. Agriculture was and in many features still is traditional, self-supplying, and hard-work. The life-style has always been environmentally friendly as it has been without modern technologies. Nevertheless, modernization exploded dramatically in these villages after 1989, when the communist policies collapsed along with Romania's isolation. People from the Czech Republic have rediscovered Romanian Banat and a rather busy (agro tourism has developed there. The Czech Ministry of Foreign Affairs supports development projects for making living conditions in the village better. Simultaneously, strong migration from Banat to the Czech Republic has started. People find living conditions in the Czech Republic easier and leave hard work, poverty and unemployment. It brings huge land cover changes because people who remain cannot use all arable land, which is thus abandoned and left for the natural process. One of the distinct manifestations of globalization tendencies is the build-up of wind power plants.

Full Text Available The shock of the transition from a centralized type to a free market type economy and the fall of barriers with regard to migratory labor force in the countries of Central and Eastern Europe, after the fall of communist regimes in the early 1990s, have led to national companies modeling, producing a new configuration of Europe, under the banner of cooperation and common values. If in the case of Romania before 1989 we were dealing with migration restriction in the forthcoming period communism we are witnessing a massive flow of migration of the labor force, its own citizens leaving national territory in favor of establishing either temporary or definitive in Europe or in countries outside the European Union. The term migration has exceeded the strictly considered academic environment, becoming a popular subject, commonly used by the media and the population, but largely minimized by the Romanian political class. Given its particular importance on the socio-economic, cultural and political development, the purpose of this study is to get a better understanding of the magnitude of the Romanian migration and the causes that have led to its genesis and stimulation. Why people choose to emigrate, which are the motives which cause them to adopt this behavior, which are the countries of destination and which are the clichés faced by Romanian migrants there, what are the consequences of such a process, these are the questions to which we want to have an answer. Literature in the field, rigorous studies of visiting scientists from the various areas, the statistical data from the various publications by the National institute of Statistics and online media sources have been given a picture of the phenomenon being investigated, and which have been added to the data collected as a result of the application of a questionnaire in the Romanian community from the United Arab Emirates. This will highlight a reaction in the group, namely the run away from the

The activity concentrations of 40 K, 226 Ra and 232 Th in the commonly used building materials collected from Xiangyang were measured using NaI (Tl) gamma spectrometer. The radioactivity values of 40 K, 226 Ra and 232 Th in the studied samples ranged from 130.5 to 1006.3, 8.4 to 164.0, and 8.7 to 145.6 Bq kg -1 , respectively. The concentrations of these radionuclides have been compared with the typical published world values. Radium equivalent activity, external and internal hazard indexes, external and internal exposure indexes, indoor air absorbed dose rate and annual effective dose rate have been calculated to assess the potential radiological hazard associated with natural radionuclides in the studied materials. The calculated values of all the assessed indices in the analyzed building materials except for fly ash are below the internationally accepted limits indicating that these building materials can be safely used in dwellings construction and do not lead to any significant radiation exposure to occupants. Nevertheless, the annual effective dose rate values of all fly ash samples, external and internal hazard indexes values in most fly ash samples exceed the recommended values. It is, therefore, desirable to regularly monitor the natural radioactivity level of the building materials products made from fly ash.

2006-10-01

Full Text Available This study provides a methodological analysis to evaluate the regulation strategy in Romanian natural gas sector. The market oriented reforms are not only associated with the gap between internal prices and world prices. In the same time, the market oriented reforms are mixed with the other forms of government intervention. The industry network theory provides a good pillar for maintaining natural monopoly in public utilities. The conclusions which are presented in this article offer a good theory for the activity of the National Authority of Regulation in Romanian natural gas sector.

2016-08-01

Multinational companies in Romania have imposed the use of the predominant language, in most cases - English, in professional communication. In contexts related to workplace communication, the main motivation for foreign borrowings is the need to denote concepts and activities. The article focuses on the English language as a wide source for a great number of innovations both at the lexical and the morphological level in the Romanian vocabulary related to business and technology. The aim of the paper is to demonstrate that Romanian language displays a natural disposition towards adopting and adapting foreign words, especially borrowed English terms, in the field of computer science and business without endangering its identity.

Highlights: • This study is to quantify the building and terrain effects on the atmospheric dispersion. • Statistical methods with AERMOD-PRIME and CFD were used. • To assess the risk in nuclear power plants, terrain and building effects have to be considered. - Abstract: This study identified the terrain and building effects on the atmospheric dispersion of radioactive materials at the Wolsong Nuclear Site. To analyze the atmospheric dispersion of radioactive materials, the AERMOD-PRIME model, CFD model and meteorological data from 2010 were used. The terrain and building effects on the atmospheric dispersion of radioactive materials within a 1 km radius of the site were statistically significant. The maximum concentration of the radioactive material increased by 7 times compared to the concentration when the terrain and building effects were not considered. It was found that the terrain and building influenced the decrease in the concentration of radioactive material in a concentric circle with a 914 m radius from the center of the site. The concentration of radioactive material in a concentric circle with a 350 m radius was two-times higher than the concentration estimated at the backside of the building, which is the downwind side, without any consideration of the terrain and building effects. In consideration of the Korean situation, in which multiple nuclear reactors are built on the same nuclear site, it is necessary to evaluate the risk that may affect workers and nearby residents by reflecting the terrain and building effects

A variety of factors affect the energy and CO{sub 2} balances of building materials over their lifecycle. Previous studies have shown that the use of wood for construction generally results in lower energy use and CO{sub 2} emission than does the use of concrete. To determine the uncertainties of this generality, we studied the changes in energy and CO{sub 2} balances caused by variation of key parameters in the manufacture and use of the materials comprising a wood- and a concrete-framed building. Parameters considered were clinker production efficiency, blending of cement, crushing of aggregate, recycling of steel, lumber drying efficiency, material transportation distance, carbon intensity of fossil fuel, recovery of logging, sawmill, construction and demolition residues for biofuel, and growth and exploitation of surplus forest not needed for wood material production. We found the materials of the wood-framed building had lower energy and CO{sub 2} balances than those of the concrete-framed building in all cases but one. Recovery of demolition and wood processing residues for use in place of fossil fuels contributed most significantly to the lower energy and CO{sub 2} balances of wood-framed building materials. We conclude that the use of wood building material instead of concrete, coupled with greater integration of wood by-products into energy systems, would be an effective means of reducing fossil fuel use and net CO{sub 2} emission to the atmosphere.

Sustainability and Competitiveness of Romanian Farms through Organic Agriculture

Directory of Open Access Journals (Sweden)

Mirela Ionela Aceleanu

2016-03-01

Full Text Available Currently, the development of any sector involves respecting the principles of sustainability, which means economic, social and environmental development. Moreover, organic farming is a very important field for ensuring sustainable development. Romania has great potential for the development of organic agriculture, especially due to the large number of available farmland and reduced use of fertilizers and other chemicals. However, the development of organic farming in Romania is in an early stage, due to the numerous problems that Romanian agriculture is still facing. Concern for the environment should be reflected at the level of production processes and consumption. As market demand influences and stimulates production, we can ask the question to what extent stimulating the consumption of organic products through green marketing can boost organic agriculture development and competitiveness of Romanian farms. Using several methods of research, such as analysis, synthesis, comparison, statistical methods and by calling on studies, reports and data series on organic farming in the EU and Romania, this paper highlights Romania's position in terms of the level of development of organic agriculture and recommends several ways to improve the outcomes obtained by Romania in the field. Moreover, based on regression equations, the trend of convergence of Romanian organic agriculture development in relation to the EU countries is analysed. The paper demonstrates that one of the measures that can be taken by Romanian farms is green marketing strategy development that can stimulate both consumption and production of organic products. Therefore, with increasing interest in the development of organic agriculture in Romania, green marketing can play an increasingly important role in promoting the benefits of consuming organic products, thus contributing to business development of organic products as well as to the development of Romanian agriculture

Moisture measurements in building materials with microwaves; Rakennusmateriaalien kosteusmittauksia mikroaalloilla

In order to assess the condition and evaluate the reliability of buildings and structures, it is essential to establish the moisture condition of the floor and other structural elements of the building. NDT-methods are increasingly being used for such moisture measurements because they do not cause any damage to the building under investigation. Microwave transmission is one of the NDT-methods and has been in use for several years. In this report, the applicability of the microwave method for measuring moisture in different building materials was investigated. This method has been successfully used at BAM for repeated moisture measurements in brick and sandstone material. This project also included other materials, such as concrete, sand, gravel, insulation and wood. At the same time, information was gathered about in situ moisture determination of building materials with a microwave moisture measuring system. The equipment used in this research has been developed at BAM over the last few years. The method requires two parallel boreholes in the specimen in which two microwave antennae can be moved. The moisture content in the material can be calculated from the microwave intensity transmitted between the two boreholes. Moisture profiles along the boreholes can be obtained by moving the antennae in steps along the length of the boreholes and taking measurements at each step. Special care must be taken while drilling the holes for the antennae, as this process must not affect the moisture condition in the specimen, and the boreholes must be made as parallel to each other as possible. The microwave frequencies used in the laboratory measurements ranged from 8 to 16,5 GHz in steps of 0,5 GHz. The diameters of the antennae were between 7 and 9 mm, and of the boreholes between 8 and 12 mm. Except for the concrete specimen, all the specimens were measured using plastic tubes in the boreholes. The moisture content measured by the microwave technique was verified by the

Enhancement of global flood damage assessments using building material based vulnerability curves

Englhardt, Johanna; de Ruiter, Marleen; de Moel, Hans; Aerts, Jeroen

2017-04-01

This study discusses the development of an enhanced approach for flood damage and risk assessments using vulnerability curves that are based on building material information. The approach draws upon common practices in earthquake vulnerability assessments, and is an alternative for land-use or building occupancy approach in flood risk assessment models. The approach is of particular importance for studies where there is a large variation in building material, such as large scale studies or studies in developing countries. A case study of Ethiopia is used to demonstrate the impact of the different methodological approaches on direct damage assessments due to flooding. Generally, flood damage assessments use damage curves for different land-use or occupancy types (i.e. urban or residential and commercial classes). However, these categories do not necessarily relate directly to vulnerability of damage by flood waters. For this, the construction type and building material may be more important, as is used in earthquake risk assessments. For this study, we use building material classification data of the PAGER1 project to define new building material based vulnerability classes for flood damage. This approach will be compared to the widely applied land-use based vulnerability curves such as used by De Moel et al. (2011). The case of Ethiopia demonstrates and compares the feasibility of this novel flood vulnerability method on a country level which holds the potential to be scaled up to a global level. The study shows that flood vulnerability based on building material also allows for better differentiation between flood damage in urban and rural settings, opening doors to better link to poverty studies when such exposure data is available. Furthermore, this new approach paves the road to the enhancement of multi-risk assessments as the method enables the comparison of vulnerability across different natural hazard types that also use material-based vulnerability curves

The natural level of radioactivity in building materials is one of the major causes of external exposure to γ-rays. The primordial radionuclides in building materials are one of the sources of radiation hazard in dwellings made of these materials. By the determination of the radioactivity level in building materials, the indoor radiological hazard to human health can be assessed. This is an important precautionary measure whenever the dose rate is found to be above the recommended limits. The aim of this work was to measure the specific activity concentration of 226 Ra, 232 Th and 40 K in commonly used building materials from Namakkal, Tamil Nadu, India, using gamma-ray spectrometer. The radiation hazard due to the total natural radioactivity in the studied building materials was estimated by different approaches. The concentrations of the natural radionuclides and the radium equivalent activity in studied samples were compared with the corresponding results of different countries. From the analysis, it is found that these materials may be safely used as construction materials and do not pose significant radiation hazards. - Highlights: ► Most of the building materials contain natural radionuclides. ► The radioactivity level in building materials is used to assess the radiological hazards to human. ► We present the results for the measured activities and radiation hazards of building materials. ► We report that the studied building materials do not pose any significant radiation hazard.

Research and Development of solar cell frame. Study on solar cell array solid with building material-business building

Energy Technology Data Exchange (ETDEWEB)

1986-08-01

This is a NEDO annual report for 1985. A feasibility study was carried out from the viewpoints demanded both from the building material side and the solar cell. Evaluation from the technical, institutional, and economical viewpoints indicated the possibility of using a roof material solid with carbon-fiber-reinforced concrete and a curtain wall. The solar cell module was verified as a building material to be resistant against the external force, water, and heat. A problem left is how to enlarge the module. Integrated use of CFRC (Carbon Fiber Reinforced Concrete) and a cell of maximum size (1,240 x 700 mm), which is industrially available, can be expected. Present solar cell array can be utilized as a building material as it is for a curtain wall. Cost calculation of the CFRC solid roofing material indicates 276 yen/KWH for 15 years depreciation, 10 % residual value, and 8% annual interest, which is a little expensive, but this cost may be applicable to the use as a curtain wall.

2005-01-01

Eight kinds of building materials collected from Xi'an, China were analyzed for the natural radioactivity of 226 Ra, 232 Th and 40 K using γ-ray spectroscopy. The concentrations of 226 Ra, 232 Th and 40 K in the selected building materials ranges from 19.5 to 68.3Bqkg -1 , 13.4 to 51.7Bqkg -1 and 63.2 to 713.9Bqkg -1 , respectively. The measured activity concentrations for these natural radionuclides were compared with the reported data of other countries and with the world average activity of soil. The radium equivalent activities (Ra eq ), external hazard index (H ex ) and the internal radiation hazard index (H in ) associated with the natural radionuclides were calculated. The Ra eq values of all building materials are lower than the limit of 370Bqkg -1 , equivalent to a γ-dose of 1.5mSvyr -1 . The values of H ex and H in are less than unity

POLITICAL ANGLES IN THE ROMANIAN ONLINE MEDIA ABOUT THE REFUGEES' CRISIS AND ISLAM. TRAIAN BĂSESCU CASE

Directory of Open Access Journals (Sweden)

Antonio MOMOC

2016-06-01

Full Text Available The public perception in Romania regarding the Syrian refugees has dramatically changed within a few months in the sense of rejecting the idea of receiving immigrants on Romanian territory. In August 2015 the polls indicated that Romanians were in favour of accepting the immigrants, while in September 2015 more than half of the respondents declared they were against receiving refugees. What kind of narrative was used by the Romanian politicians to cover the “refugee/migrant crisis”? This study tried to establish the ways in which social media have been changing Romanian perception related to refugees, asylum seekers and migrants. In this research, we have monitored discourses of xenophobia and poisonings that occurred in the Romanian social media. A few Romanian politicians have aggravated the immigrant related debate via their personal social media accounts. The former Romanian President, Traian Băsescu, was one of them. As the EU public debates on whether the refugees’ quotas should be mandatory or volunteer have scaled up, the people's perception was altered immediately after the discourse about rejecting the refugees has intensified in the online environment.

2016-01-01

In the present work radioactivity in building materials (granite) central Sudan was evaluated. In general the building materials used in Sudan are derived either from rocks or soil. These contain trace amounts of naturally occurring radioactive materials(NORMs), so it contains radionuclides from uranium and thorium series and natural potassium. The levels of these radionuclides vary according to the geology of their site of origin. High levels increase the risk of radiation exposure in homes(especially exposure due to radon). Investigation of radioactivity in granite used of the building materials in Sudan is carried out, a total of 18 major samples of granite have been collected and measured using X- ray fluorescence system (30 mci). The activity concentrations have been determined for uranium ("2"3"8U), thorium ('2"3"2Th) and potassium("4"0K) in each sample. The concentrations of uranium have been found to range from 14.81 Bq/kg to 24.572 Bq/kg, thorium between 10.02 Bq/kg and 10.020-84.79 Bq/kg and the potassium concentration varies between 13.33 Bq/kg to 82.13 Bq/kg. Limits of radioactivity in the granite are based on dose criteria for controls. This study can be used as a reference for more extensive studies of the same subject in future. (Author)

MADALINA MORARU (BUGA

2012-05-01

Full Text Available The following paper intends to reveal the involvement of women into coining efficient communication campaigns for different product categories promoted on the Romanian market. Product consumption explicitly depends on target interests and social integration considering its division into two directions according to age groups (the old generation and the young, “new media generation” after the 1989 Revolution. Our main purpose consists in identifying female profiles in Romanian advertising starting from Geert Hofstede’s theory. He created a fivedimension model (power distance, individualism/collectivism, gender of nations, uncertainty avoidance, long/short-term orientation of national culture, by analyzing local and global brands, on the one hand, and different product categories (dairy, coffee and chocolate, drugs, banks and insurance, mobile phones, home appliances, on the other. This paper will apply the content analysis method, whose purpose is to reveal the Romanian identity promoted by the female characters of at least 50 TV commercials. In order to get a wealth of information, this study focuses on important aspects such as tradition, independence vs. involvement in family responsibilities, authority vs. subordination, living environment (city or countryside, as well as relationships with men and children. At the end of this research, we expect to reach two important goals. The first one is to establish a relationship between product categories, local identity, and the Romanian target, which is still in transition after the Anti- Communist Revolution. As for the second goal, we hope to discover some female patterns which are very well exploited in Romanian advertising based on cultural and social background. The hypothesis that strongly supports this research is that women have an essential role in preserving local identity, appealing to the Romanian consumer in commercials created especially for them.

Five cement- and five lime-based building materials were examined in an environmental chamber for their emissions of Volatile Organic Compounds (VOCs). Typical VOCs were below detection limits, whereas not routinely analysed VOCs, like neopentyl glycol (NPG), dominated the cement-based products emissions, where, after 72 h, it was found to occur, in levels as high as 1400 μg m(-3), accounting for up to 93% of total VOCs. The concentrations of NPG were not considerably changed between the 24 and 72 h of sampling. The permeability of building materials was assessed through experiments with a dual environmental chamber; it was shown that building materials facilitate the diffusion of chemicals through their pores, reaching equilibrium relatively fast (6 h).

The activity concentrations of {sup 40}K, {sup 226}Ra and {sup 232}Th in the commonly used building materials collected from Xiangyang were measured using NaI (Tl) gamma spectrometer. The radioactivity values of {sup 40}K, {sup 226}Ra and {sup 232}Th in the studied samples ranged from 130.5 to 1006.3, 8.4 to 164.0, and 8.7 to 145.6 Bq kg{sup -1}, respectively. The concentrations of these radionuclides have been compared with the typical published world values. Radium equivalent activity, external and internal hazard indexes, external and internal exposure indexes, indoor air absorbed dose rate and annual effective dose rate have been calculated to assess the potential radiological hazard associated with natural radionuclides in the studied materials. The calculated values of all the assessed indices in the analyzed building materials except for fly ash are below the internationally accepted limits indicating that these building materials can be safely used in dwellings construction and do not lead to any significant radiation exposure to occupants. Nevertheless, the annual effective dose rate values of all fly ash samples, external and internal hazard indexes values in most fly ash samples exceed the recommended values. It is, therefore, desirable to regularly monitor the natural radioactivity level of the building materials products made from fly ash.

The adsorption/desorption of volatile organic compounds (VOCs) on interior building material surfaces (i.e., the sink effect) can affect the VOC concentrations in a building, and thus need to be accounted for an indoor air quality (IAQ) prediction model. In this study, the VOC adsorption/desorption characteristics (sink effect) were measured for four typical interior building materials including carpet, vinyl floor tile, painted drywall, and ceiling tile. The VOCs tested were ethylbenzene, cyclohexanone, 1,4-dichlorobenzene, benzaldehyde, and dodecane. These five VOCs were selected because they are representative of hydrocarbons, aromatics, ketones, aldehydes, and chlorine substituted compounds. The first order reversible adsorption/desorption model was based on the Langmuir isotherm was used to analyze the data and to determine the equilibrium constant of each VOC-material combination. It was found that the adsorption/desorption equilibrium constant, which is a measure of the sink capacity, increased linearly with the inverse of the VOC vapor pressure. For each compound, the adsorption/desorption equilibrium constant, and the adsorption rate constant differed significantly among the four materials tested. A detailed characterization of the material structure in the micro-scale would improve the understanding and modeling of the sink effect in the future. The results of this study can be used to estimate the impact of sink effect on the VOC concentrations in buildings.

A metric for characterizing the effectiveness of thermal mass in building materials

Talyor, Robert A.; Miner, Mark

Highlights: • Proposes a metric for interior thermal mass materials (floors, walls, counters). • Simple, yet effective, metric composed of easily calculated ‘local’ and ‘global’ variables. • Like Energy Star, the proposed metric gives a single number to aid consumer choice. • The metric is calculated and compared for selected, readily available data. • Drywall, concrete flooring, and wood paneling are quite effective thermal mass. - Abstract: Building energy use represents approximately 25% of the average total global energy consumption (for both residential and commercial buildings). Heating, ventilation, and air conditioning (HVAC) – in most climates – embodies the single largest draw inside our buildings. In many countries around the world a concerted effort is being made towards retrofitting existing buildings to improve energy efficiency. Better windows, insulation, and ducting can make drastic differences in the energy consumption of a building HVAC system. Even with these improvements, HVAC systems are still required to compensate for daily and seasonal temperature swings of the surrounding environment. Thermal mass inside the thermal envelope can help to alleviate these swings. While it is possible to add specialty thermal mass products to buildings for this purpose, commercial uptake of these products is low. Common building interior building materials (e.g. flooring, walls, countertops) are often overlooked as thermal mass products, but herein we propose and analyze non-dimensional metrics for the ‘benefit’ of selected commonly available products. It was found that location-specific variables (climate, electricity price, material price, insolation) can have more than an order of magnitude influence in the calculated metrics for the same building material. Overall, this paper provides guidance on the most significant contributors to indoor thermal mass, and presents a builder- and consumer-friendly metric to inform decisions about

Full text: One of possible method of realization of the terrorist acts is using gases and liquids, which easily permeate through the constructive materials of walls, floor, ceiling, roof, etc. into buildings by the capillary action of the pores. Toxic volatile organic compounds, organic and inorganic gases, radioactive elements, especially, which emits alpha particles can be used as the dangerous substances. Increased ventilation may help in removing the gases, but can actually increase the gases level by increasing the suction through the pores of concrete. If the gases and liquids are soluble in water and are easily volatilized from it, they can also get by groundwater up to underground structures and penetrate inside through opening and pores in concrete or pushed by hydrostatic pressure. The purpose of this work is creating a method to reduce concentration of toxic and radioactive gases in homes, buildings, underground buildings, tunnels, hangars, garages, bomb shelters, etc. The most effective method to prevent penetration of radionuclides into premises of buildings and underground structures through walls, roofs, floors is using special chemicals, which seal micropores inside the construction materials against gases. Worked out chemicals which consist of blend of polymeric compounds are described in the paper. Radioactive gases permeability in constructive materials after treatment by chemicals was studied. Influence of types of cement, sand and gypsum, preliminary treatment by different chemicals, different types of polymeric compounds, time between treatments, moisture of materials, time between preparation of chemicals and treatment of materials (aging of chemicals), time between treatment of concrete and testing (aging of treated concrete) were examined. Experiments have shown that our method allows reducing the coefficient of gas permeability 200 - 400 times

Development of an Assessment Method for Building Materials Under Euratom Scope.

Science.gov (United States)

de With, Govert

2017-11-01

In 2013, the European Commission published its basic safety standards for protection against the dangers arising from exposure to ionizing radiation (Council Directive 2013/59/Euratom)-also known as EU-BSS. As a result, the use of raw materials with potentially elevated activity concentrations such as fly ash, phosphogypsum, and slags will now fall under EU-BSS scope when applied in building materials. In light of this new policy, a variety of tools are available to assess compliance with the 1-mSv y reference level for building materials. At the heart of these tools is a gamma-spectrometric determination of the naturally occurring radionuclides Ra, Th, and K in the material of concern. As a large number of construction products contain a certain amount of the raw material that falls under the scope of the EU regulation, this policy will lead to substantial measurement of building materials that pose little radiation risk. For this reason, a method is developed to enable assessment against the 1-mSv value not on the basis of gamma-spectrometric analysis but rather based on the product's material composition. The proposed method prescribes a maximum permitted content of raw materials with potentially elevated activity concentrations in terms of a weight percentage of the end product, where the raw materials of concern are defined as those listed in Annex XIII of the EU-BSS. The permitted content is a function of the product's surface density. Therefore, a product with a low surface density of up to 25 kg m can consist of nearly 100% raw materials with potentially elevated activity concentrations, and this percentage drops to around 15% for products with a surface density of around 500 kg m. Building materials that comply with these requirements on product composition are exempt from testing, while products that do not comply must perform regular gamma-spectrometric analysis. A full validation and testing of the method is provided. In addition, the paper discusses

2018-01-01

Full Text Available This paper presents a different point of view on the conservation of the built heritage, adding ionizing radiation to the most well-known digital documentation dataset. Igneous building materials characterize most of the built heritage in the Campania region, and in a large part of southern Italy. The ionizing radiations proceeding from these materials can produce stochastic biological effects on the exposed living beings. The research team designed and tested a technical-scientific protocol to survey and analyse this natural phenomenon in association with the use of geological material for building purposes. Geographical Information Systems (GISs, City Information Modelling (CIM, and Building Information Modelling (BIM are the digital tools used to manage the construction entities and their characteristics, and then to represent the thematic data as false-colour images. The emission spectra of fair-faced or plastered materials as a fingerprint of their nature is proposed as a non-invasive method. Due to both the huge presence of historical buildings and an intense touristic flow, the main square of Pompei has been selected as a study area.

Within a radiological survey of the building materials used in the urban dwellings in the central region of Egypt, the uranium concentration in 80 representative samples of raw and fabricated building materials are determined using laser fluorimetry technique. For 40 samples from the studied raw building materials of sand, gravel, gypsum, lime-stone, granite and marble the determined uranium concentration values range between 0.3 and 3.6 ppm for all these samples except for one type of granite having the corresponding value of 7.8 ppm. For 37 samples from studied fabricated building materials of normal cement, clay brick, sand brick, tiles and ceramic plates the determined uranium concentration values range from 0.5 to 3.4 ppm. The corresponding values for three types of iron cement are 3.1, 6.1 and 9.3 ppm. The radium-226 content (of the uranium-238 series) in the same samples was determined using high resolution gamma-ray spectrometers based on HP Ge-detectors. The data obtained by the two techniques are in good agreement for the majority of the studied samples. (author)

Full Text Available To know and to understand the factors within a financial system that significantly influences the institutions behaviour and the market responses to the central bank actions is of great importance for the monetary authorities and for the achievement of their monetary policy objectives. In Romania, the National Bank must pay special attention to financial institutions given their significant role in the process of financial intermediation (bank-based system. This study aims to conduct an investigation of the main coordinates of the Romanian financial system that are relevant for the study of the monetary policy transmission mechanism. The study focuses on the following features of the Romanian financial system: financial deepening, the existence of a bank-based system, the concentration degree of the Romanian banking sector, the balance sheet structure of monetary financial institutions and the soundness of the banking system. The study also considers the effects of the recent financial market turmoil on the financial system. The span of the empirical study covers the period after 2000 but brings to the forefront the period before and after October 2008. We believe that this research provides useful information for a future analysis of the Romanian monetary policy transmission mechanism.

Fungal Microbiomes Associated with Green and Non-Green Building Materials.

Water-damaged buildings can lead to fungal growth and occupant health problems. Green building materials, derived from renewable sources, are increasingly utilized in construction and renovations. However, the question as to what fungi will grow on these green compared to non-green materials, after they get wet, has not been adequately studied. By determining what fungi grow on each type of material, the potential health risks can be more adequately assessed. In this study, we inoculated green and non-green pieces of ceiling tile, composite board, drywall, and flooring with indoor dust containing a complex mixture of naturally occurring fungi. The materials were saturated with water and incubated for two months in a controlled environment. The resulting fungal microbiomes were evaluated using ITS amplicon sequencing. Overall, the richness and diversity of the mycobiomes on each pair of green and non-green pieces were not significantly different. However, different genera dominated on each type of material. For example, Aspergillus spp. had the highest relative abundance on green and non-green ceiling tiles and green composite boards, but Peniophora spp. dominated the non-green composite board. In contrast, Penicillium spp. dominated green and non-green flooring samples. Green gypsum board was dominated by Phialophora spp. and Stachybotrys spp., but non-green gypsum board by Myrothecium spp. These data suggest that water-damaged green and non-green building materials can result in mycobiomes that are dominated by fungal genera whose member species pose different potentials for health risks.

Long-term exposure to radon increases the risk of developing lung cancer. There is considerable public concern about radon exhalation from building materials and the contribution to indoor radon levels. To address this concern, radon exhalation rates were determined for 53 different samples of drywall, tile and granite available on the Canadian market for interior home decoration. The radon exhalation rates ranged from non-detectable to 312 Bq m{sup -2} d{sup -1}. Slate tiles and granite slabs had relatively higher radon exhalation rates than other decorative materials, such as ceramic or porcelain tiles. The average radon exhalation rates were 30 Bq m{sup -2} d{sup -1} for slate tiles and 42 Bq m{sup -2} d{sup -1} for granite slabs of various types and origins. Analysis showed that even if an entire floor was covered with a material having a radon exhalation rate of 300 Bq m{sup -2} d{sup -1}, it would contribute only 18 Bq m{sup -3} to a tightly sealed house with an air exchange rate of 0.3 per hour. Generally speaking, building materials used in home decoration make no significant contribution to indoor radon for a house with adequate air exchange.

International Nuclear Information System (INIS)

Nemec, T.; Rant, J.; Apih, V.; Glumac, B.

1999-01-01

Neutron radiography (NR) is a useful non-destructive method for determination of hydrogen content in various building and technical materials. Monitoring of transport processes of moisture and hydrogenous liquids in porous building materials is enabled by fast, quasi-real-time NR methods based on novel imaging plate neutron detectors (IP-NDs). Hydrogen content in the samples is determined by quantitative analysis of measured profiles of neutron attenuation in the samples. Detailed description of quantitative NR method is presented by the authors in another accompanying contribution at this conference. Deterioration of building materials is originated by different processes that all require presence of water therefore it is essential to limit or prevent the transport of water through the porous material. In this presentation, results of a study of clay brick impregnation by silicone based hydrophobic agents will be presented. Quantitative results obtained by NR imaging successfully explained the processes that occur during the impregnation of porous materials. Efficiency of hydrophobic treatment was quantitatively evaluated

2006-05-01

Full Text Available This paper presents the conclusions resulted from an intonational analysis of Romanian Yes-No questions. The recent analysis results consist in dividing and structuring the F0 curves into intonational units. Each intonational unit is described by a tone sequence using ToBI labels used in annotation of the most important phonetic events: pitch accents and boundary tones. The authors of the present study propose a description of the resulted patterns for F0 contour in terms of intonational units structures described by their tone sequence. We consider this description suitable for the variety of melodic contours resulted from different speakers and different focalizations in their utterances. In paragraph 3, the paper presents the intonational variants resulted from our speech corpus analysis. The conclusions of Yes-No question analysis are important for linguistic studies and in Romanian speech synthesis.

Following through the key components of an institutionalised party system, the inquiry looks at the stability of interparty competition in Romania and the depth of its parties’ roots in society. These components are measured through such indicators as electoral volatility or the cohesiveness of the ideological preferences. Their levels suggest that the Romanian party system isn’t fully instituionalised, with fluctuating volatility and a rather incohesive ideological positioning of both voters and parties. This paper argues that in response to the double challenge of poor institutionalisation of the political parties and the party system as a whole, informal remedies, such as patronage of public jobs, or proprietary use of state resources, become highly attractive solutions for electoral success.

Investigation of radioactivity content of commonly used building materials in Khartoum State is carried out during the year 2010. A total of 25 samples of natural and manufactured materials from different types of building materials have been collected and measured using gamma spectrometry system. The activity concentrations have been determined for radium (2''2''6''Ra), thorium (''2'3''2Th) and potassium (''4''0K) in each sample. The concentrations of radium (represents activity of uranium and its decay series) have been found to rang from 2.8 Bq/kg in (gravel) to 108.2 Bq/kg (porcelain), thorium between 48 and 302 Bq/kg and the potassium concentration varies between 82.3 Bq/kg in (gravel) to 1413.3 Bq/kg in (marble). The activity index has also been calculated and found that it is less than 1 (mean value of 0.77 range between 0.33 and 1.97), and less than 6 for surface materials. The results have been compared with European previous studies. It is concluded that the measured radioactivity of building materials are within acceptable levels and dose not poses any risk from radiation protection point of view. (Author)

It seems that from the present Moldavian Republic to the rivers Bug and Dnieper the sheep production was of sedentary type, connected with some local Romanian inhabitants. It see also that over the Dnieper the breed presence was connected also with the transhumance practiced up to 1918 by the Transylvanian Romanian transhumance shepherds, some of them organizers after 1918 Romanian of sheep breeds association in Crimea and North Caucasus area. The official statistics from 1925 year registered in the former SSSR (without Bassarabia some 259,324 Romanians. Different historical sources estimated a higher number (1.2 million, 600,000 just in Siberia A possible explanation of founded sheep and man presence in this area can be the fact that it was the antique borderland between Thraco-Dacia and Scythia border, and the Walachian (=Romanian sheep were the sheep of Thraco-Geto-Dacs, Romanian ancestors. Transylvanian transhumance and Romanian from SE Romania introduced later Tsigai in North Pontic, this breed being introduced later by Roman in Carpathian bend.

Full Text Available Our paper provides an insight into the universe of Russian multinationals and their influence upon the Romanian economy. Even if statistical data on foreign direct investment stock by country of origin do not prove the existence of Russian capital in Romania, it is a fact that the high values of foreign direct investment stock from the Netherlands, Austria, Germany or Switzerland are largely due to the investment projects undertaken in Romania by Russian multinationals. Despite the lack of relevant statistical data, we can say that the impact of Russian MNC’s on the Romanian economy is huge. Among positive influences we can mention: global employment opportunities for highly qualified workforce in the region; the transfer of advanced technologies to Romanian enterprises and the local markets; the awareness of business partners and public opinion on social responsibility; the insert of higher performance standards, competitiveness and managerial ethics.

-structural indicators and compare it with the structural indicators of competition. In particular, we measure competition using Lerner index and the H-statistic, indicators what are estimated using bank-level data and are compared with a standard market structure measure of concentration like HHI and CR5. There are no other studies that measure both structural and non-structural competition indicators for Romanian banking sector. Also, our assessment contains a period of seven years including the begging of the implications of the present international financial crises on Romanian banking sector. The structural indicators show continuous increase of competition in the Romanian banking system. Lerner index and H statistic demonstrate that Romanian banking system is characterized by monopolistic competition and relatively competitive practices. Personnel cost, operational cost and financial cost are statistically significant at conventional levels, which imply good fit of the revenue equations. The results also demonstrate that excess fixed assets do not generate abnormal revenue.

Finland might seem to have lower stone heritage compared to other southern European countries, but it has been the main exporter of dimension stone to the majestic buildings that made St.Petersburg a recognized cultural heritage. In Finland, though, the stone seems undervalued. The only dramatic and predominant stone buildings are those of agencies and administrations located in the towns, where the stone has been used to impress and symbolize value. Romantic style used massive bossy stone in building's full height and created fine traditional carvings. Otherwise the communities have mainly built settlements in contact with the nature, with materials easily available and of low cost, following architectonical trends of the periods and producing interesting stone details. During the past years, research has been conducted on historical buildings interconnecting scientific and artistic approach to evaluate material durability and cultural relevance of the artifacts. Generally until mid 20th century the stone has been traditionally used massive for basements and walls. The materials still present good mechanical characteristics and most often the weathering level after hundreds of years of exposure had reached only the first millimeters from the curst. Instead the old methodology for deposit exploitation has left visible signs on the buildings. Some examples are visible from Kuopio. The exploitation of small, easy-to-reach surface deposits, even if planned by local experts, has affected quality and appearance of historical buildings. As an example the excavation of shallow quarries where also weathered crop was kept as a product has characterized the basement of the Niirala school that presents change in colors due to original material more than to weathering on site. Fissuring is also visible on a couple of blocks while marks on the rocks depict the old excavation method. Most often the deposits had been in the vicinities, frequently hidden by further construction

The practice of implementation demonstrates that the perception of many executives in the Romanian private enterprises regarding the set of tools to improve processes and assimilation of lean philosophy is not a very favorable and encouraging one. It can be said that only some large enterprises had successfully introduced in their daily practice and organization the improvement principles, the operational optimization and the elimination of waste sources. In the SMEs, and especially in the services the experiences are isolated, but they have demonstrated the usefulness (the frequency of saving goals indicate, indeed, the need for proliferation of continuous improvement principles. Regarding the public organizations, the implementation of the new management system of designing and operating the current practices is pretty unknown, accepted at declarative level, but becomes, when is planned and implemented rather a burden on managers who should take on this challenge. Both in public management and private management, today the focus is on people and relationships (processes and projects, starting of course with the work organization. The good practices successfully proved in the private management in the recent decades are transferred today to public institutions; and the Romanian public organizations tend to adapt, also in terms of processes optimization. The study aims to analyze the functioning of the hypothetical management system of processes improvements, respectively the applying of lean tools and principles within the public Romanian institution.

2001-01-01

Nuclearelectrica operates at Cernavoda NPP a CANDU 6 unit. The production performances and some technical indicators are presented. The paper introduces the players of the new-born Romanian energy market, where Nuclearelectrica acts as a significant producer, and. gives a short description of the current market mechanisms. The specific features of a producer operating a single nuclear unit, related to both technical and economical terms, are itemized; they are considered in the market rules issued by the Romanian Electricity Regulatory Authority - ANRE. Following these rules, Nuclearelectrica concluded with Electrica, the main energy supplier to final consumers, a long-term energy wholesale contract for all the generated by Cernavoda 1 electricity, based on the so-called Power Purchase Agreement model, where a large part of the risk related to the power sales is borne by the buyer. On the same time, the existing conditions on the Romanian market proved the competitiveness of Cernavoda unit as an energy producer; hence, the above-mentioned contract provides a futile over-protection to the NPP facing the market risks. The paper presents also the critical issue of the collection of revenues for the sold electricity and the company's approach in allotting this limited revenues. In light of the completion of Unit 2 of the Cernavoda NPP, the company's strategy considers new possible contracts, with eligible customers and energy exports.(author)

Full Text Available The effect of mechanical load on the thermal conductivity of building materials in the design of envelope parts of building structures is studied. A typical building material is chosen in the practical investigation of this effect, namely the cement mortar. It is concluded that in the range of hygroscopic moisture content, lower levels of mechanical load, typically up to 90 % of compressive strength (CS, are not dangerous from the point of view of worsening the designed thermal properties, but in the overhygroscopic region, the load as low as 57 % of CS may be dangerous. The higher levels of loading are found to be always significant because they lead to marked increase of thermal conductivity which is always a negative information for a building designer.

Full Text Available Entrepreneurship has begun to grapple with the global economic and financial crisis, and entrepreneurs have become "heroes" capable of delivering impetus to fragile economies. Small and innovative companies account for 99% of all Europe's active companies and offer 66% of available jobs. In the context of a worrying unemployment rate that persists in many countries of the world, entrepreneurship has become a viable solution to economic problems. Entrepreneurship can not be defined precisely, and the multidimensionality and homogeneity of the concept makes it very difficult to generalize the conclusions of studies for regions other than those for which they were originally developed. The objective of the present study is to carry out a comprehensive analysis of the Romanian entrepreneurial ecosystem and the factors that have the power to stimulate it, thus allowing the design of efficient policies for the development of Romanian entrepreneurship.

To turn from a close center oriented economy to market economy required an enormous effort from the population and from the companies as well, but the real challenge is still to come. The requirements of competitiveness and innovation of the United European Market are compulsory, from the point of view of the Romanian entrepreneurs is vital for their survival and development. The studies made so far are not very promising. There are many things to be done, many problems are still not solved in the European Union. The European Union is behind its traditional competitors USA and Japan. This is why one of the major concerns of the EU is competitiveness and innovation.

The Effect of Anisotropy of Building Materials on the Moisture Transfer

2000-01-01

Full Text Available The effect of anisotropy of building materials on the moisture transfer in the design of envelope parts of building structures is studied. Two typical fibre containing plate building materials produced in the Czech Republic, Dekalux and Dekalit P, are chosen for the demonstration of this effect. Experimental results show that while for lighter Dekalit P, an order of magnitude difference in the moisture diffusivities k for the two basic orientations, i.e. along and across the plate, is observed, for the heavier Dekalux the differences in k are within the errorbar of the experimental method. As follows from the experimental results, compacting of surface layers of the plates of light fibred materials is very favorable from the point of view of moisture penetration but one should keep in mind that any local damage of the surface layer can result in a considerably faster moisture transfer in the direction along the plate.

The activity concentrations of radium, thorium and potassium can vary from material to material and they should be measured as the radiation is hazardous for human health. Thus, studies have been planned to obtain the radioactivity of ceramic building materials used in Cuddalore District, Tamilnadu, India. The radioactivity of some ceramic materials used in this region has been measured using a gamma-ray spectrometry, which contains an NaI(Tl) detector connected to multichannel analyzer. The specific activities of (226)Ra, (232)Th and (40)K, from the selected ceramic building materials, were in the range of 9.89-30.75, 24.68-70.4, 117.19-415.83 Bq kg(-1), respectively. The radium equivalent activity, absorbed gamma dose rate (D) and annual effective dose rate associated with the natural radionuclides are calculated to assess the radiation hazards of the natural radioactivity in the ceramic building materials. It was found that none of the results exceeds the recommended limit value.
